The GPSMap 60Cx features the powerful SiRF GPS navigation chip for supreme accuracy in all conditions.
You can use the 60Cx's memory card slot with preprogrammed microSD cards from Garmin (sold separately) that provide topographic maps, city streets, and nautical charts. In fact, the unit is compatible with most Garmin MapSource products including BlueChart, City Navigator, U.S. Topo 24K, and U.S. Topo and Recreational Lakes with Fishing Hot Spots. The unit comes preloaded with an Americas autoroute basemap that provides automatic routing capabilities including highways, exits, and tide data. There's also a preloaded marine point database. You can even get turn-by-turn directions when you're driving, and an integrated trip computer provides odometer, stopped time, moving average, overall average, total time, max speed, and more.
The 60Cx's 2.6-inch, 256-color TFT color display is designed to present mapping and trip information clearly and accurately in any lighting conditions. Plus, the case is lightweight, rugged, and water resistant to IEC 60529 IPX7 standards (can be submerged in one meter of water for 30 minutes). When using two AA alkaline batteries, you'll get up to 30 hours of battery life from the unit.
Another key feature of the 60Cx is the 10,000 point automatic track log; 20 saved tracks (500 points each) let you retrace your path in both directions. There's also a large-numbers option for easy viewing, as well as a dual-position display mode. The also unit includes built-in celestial tables for best times to fish and hunt, plus sun and moon calculations.
The 60Cx's trip computer provides odometer, stopped time, moving average, overall average, total time, max speed, and more. Meanwhile, a fast processor allows the 60Cx to provide quick auto-routing, turn-by-turn directions, and audio alerts when you use the optional MapSource software, which can be stored on the unit's included 64 MB microSD card. Downloading information is quick with the USB or serial port interfaces. Using the dedicated serial port, the 60Cx can share navigation instructions with repeaters, plotters, and autopilots. The four-position rocker pad and dedicated high-use buttons make navigating through the unit's features easy, even when your fingers are cold or wet.
Finally, the GPSMap 60Cx is packed with some extra fun features. An integrated outdoor calendar provides ideal hunting and fishing times, as well as moon rise/set/location information. There is a dedicated geocaching mode for those of you into the hot GPS community treasure hunt game. Finally, there are indoor/outdoor GPS games to help you and your friends enjoy the outdoors.
If you like the features of the 60Cx but require an electronic compass and a barometric altimeter, check out the Garmin 60CSx.

I'm a Very Happy Owner of the Map 60CxMar 26, 2007
By Y. Tsuchida "ABearInTheWoods"
Finally a GPS unit that simply works the way it's supposed to! Ok... I admit I am still on my honeymoon with the Garmin Map 60Cx, but so far it has worked like a dream and has exceeded my expectations.

This unit was very easy to use intuitively right out of the box. My greatest surprise was when I turned on the unit for the first time and, literally within a minute, I had locked 6 satellites! (with another 4 on the way). I just have to mention that with my previous 3 GPS units, I would have to wait 10 to 20 minutes for a lock on the minimum 3 satellites. Also, this Map 60Cx seems to keep lock well even with buildings, trees, and obstructions (whereas my previous GPS units would frustratingly lose lock when I entered a forest or even stood next to a building). This really makes the Map 60Cx a great pleasure to use. It initiates right away and keeps lock, just like it should. The displays are easy to read and interpret and it easily navigates through the different pages with simple intuitive controls (with Windows-like menus). Oh! and the colour display is great, very easy to see even without the backlight.

The difference between the Garmin GPS Map 60Cx and the Garmin GPS Map 60CSx is that the 60CSx has an electronic compass and a barometric altimeter built in and it usually costs about $30 more than the 60Cx. I opted for the 60Cx (minus the compass and altimeter) because I already had these instruments on my wrist watch, they were redundant with the GPS compass and GPS altimeter already included with the unit, and I noticed that compared to the 60CSx with an 18 hour battery life, the Map 60Cx sips power with up to a 30 hour battery life. Since the only difference between the two are these two additional instruments (compass and altimeter), I can only surmise that the exta power drain must be related to them.

As for battery life, I have not encountered any problems yet. One of my reasons for choosing this product is because it did NOT use an internal or proprietary rechargeable battery. I needed a unit that used plain, readily available, easily replaceable alkaline batteries. Rechargeable batteries do gradually lose their effectiveness over time (as another reviewer noted and attributed to the GPS unit). For me, it is easier and more reliable to just pop in 2 fresh Duracells than to wonder what the current max charge is on my rechargeables (or to pay $20-$30 for some exotic hard to find "EL-1078-4a" battery when it finally dies). This principle holds true for most consumer electronics. I try to avoid anything that uses some special battery (even a CR123 at $5 each) or worse, some specific proprietary battery made just for the device.

Another key feature that I required was waterproofness. I use my GPS unit on, in and over the water (not to mention inclement weather).

The base map is sufficient for my needs so far (hiking and geocaching), but eventually I will pick up the City Navigator software for road directions when I travel. I have seen this software in use on my friend's GPS Map 60CSx (the sister unit to the 60Cx) and despite the seemingly high additional cost, I think that for what you get, it is a good deal. Not only does it upgrade the unit into a highly effective turn by turn road navigator, but it also adds a nice city guide feature that allows you to find restaurants, gas stations, hotels, and Starbucks.

Also, having had some previous experience in law enforcement and familiarity with the California Vehicle Code, I would like to mention that the suction-cup mount accessory for the windshield is illegal in the State of California. It's CVC 26708(a).

UPDATE TO REVIEW 5/20/08:
Ok, I've used this product for a year now, the honeymoon's over... LOL... ...and I still love this product. It has performed superbly way beyond my expectations. First of all, it is indeed very rugged. I've dropped this unit many times, abraded the casing against rocks, accidentally given it impromptu dunkings in rivers and streams (not sea water yet!), and have taken it into extremes of temperature from freezing 20 below, to 120 degree desert. All I can say is, it has endured all of this abuse admirably.
Secondly, the unit when hooked up with the North America Map Pack and the car power cord (which illuminates the display constantly) serves as an excellent turn-by-turn driving GPS. Sure a bigger screen might be nice, but the GPS and directions work (with audible alerts), so I have no complaints. The big advantage is that you can easily unhook it and take the unit with you since it was designed to be handheld, thus avoiding the biggest new temptation for auto burglars.
Thirdly, much to my delight, the base maps pre-installed with the unit include INTERNATIONAL locations also! I was able to use my GPS extensively while traveling abroad 1) ensuring that I could not get "lost" and 2) keeping an automatic, constantly updating travel track log for me. This has turned out to be a wonderful extra benefit of traveling with a good GPS unit. Everywhere I went, every interesting site, every store, every restaurant, every beautiful vista, was accurately and duly recorded, and when I got home and uploaded this track log to my computer, I have a perfect travel diary of my journey. Also, marking waypoints and actually labeling them is quite easy with this GPS unit, and I've been able to do it with gloved hands. If I'm in a hurry, I'd just set a "marker" and then come back and label it later.
I burn through batteries at a consistent rate of 2 AAs every 3 or 4 days (as I power down at night), which is fine with me, to avoid all the hassles of recharging or degrading performance of rechargeables.

Any negatives??
Well, I wish that instead of suspending all functions and wasting power to give me multiple and redundant audible and lit up "pop-up" warnings that my "BATTERY IS LOW", that it would just go ahead and try to function with what little power is left until I run out of power. This is an annoying idiosyncracy of many small electronics including cell phones and iPods. I mean, I can't help but wonder how much longer these units might have functioned if they didn't expend their last gasp of power on these incessant low power warnings.
I think I would have extended the grippy rubber covering to the sides of the unit also. The times that I've dropped it were usually because it simply slipped out of my hand while holding it along the sides.
Alas, the nifty plastic belt clip did not last long under field use. Replacement clips are hard to get (and pricey too). I finally had to upgrade to a rugged military grade nylon web pouch (designed to hold a single smoke or flash-bang grenade).

It's essential that you understand the limitations of this device before buying.Mar 23, 2008
By MPB

There's no doubt that GPS technology has come a long way during the last decade. I bought this to replace my old Garmin etrex -- the 60Cx is vastly better at tracking under trees, in mountain valleys, and has a much faster processor. I use it primarily for hiking, and it is virtually impossible to become lost. Even under trees, in a valley, with the unit inside my backpack, it never lost satellite track and was never off by more than about 50 feet, comparing the hike in with the hike back.

So what's the problem? Surprisingly, the achilles heel of this mapping GPS is that there simply are no good maps for hiking/backpacking. Garmin sells a topo map set, which is completely unacceptable for any kind of in-the-field use. It lacks any kind of detail (for one thing, vertical countour lines are 150 feet, and it includes very few trails or national forest roads), and although it is nice to upload your journey to a map once you get back home and see where you went, the map itself is next to useless while hiking. Garmin makes a high-resolution topographic map set, but it covers ONLY the national parks (not even the national forests). I live in Oregon, with thousands of miles of trails, and only 1 place -- Crater Lake -- is available in high resoultion topo from Garmin. National Geographic makes a nice high-resolution map set, but it is expensive and the maps can only be loaded to a Magellan GPS, not any of the Garmins. Ditto with a GPS/topo map set from DeLorme. There is a company that has made high-resolution maps of 2 states -- Washington and Colorado -- but they require the Garmin Mapsource CD, and then they cost another hundred bucks per state on top of that.

The lack of good, high-resoultion topo maps is completely baffling, and -- at least for hiking -- makes the mapping function of this GPS completely superfluous. If I had it to do over, I think I would buy one of the newer but less expensive GPS units, like maybe a newer extrex. The extra money that you pay for the mapping capability with this unit is wasted, IMO, at least until good topo maps become available (if they every do).

Hyper Sensitive and Accurate! Just Awesome!Jan 31, 2006
By Ben Boyle
I recently received my 60cx from Amazon, and after putting it through its paces, I am extremely impressed with it. I had the older GPSMAP 60c as well, and did some comparisons between the two.

Garmin's not kidding when they say this receiver is more sensitive. I can pick up at least 5 satellite locks from INSIDE my house, about 10ft away from any window. I don't even know how it's possible, but it locks on and maintains its signal.

Navigation is awesome as well. Do yourself a favor and get the CitySelect Maps for this thing, they're great. Highly detailed. The processor even seems faster as well. The re-draw time on the maps is fast, even when at maximum detail.

Bottom Line, if you're looking for a fantastic GPS unit that is perfect for rugged activities like hiking and geocaching, and can also handle "turn-by-turn" road navigation with ease, then this is the GPS for you! Garmin has done a great job with this thing! Buy this now!

Out of the box, this thing rocks!Jul 18, 2006
By Ryan Park
Ok.. here's the deal. I've been an avid Magellan user for the past 3 years. I love my Magellan. I've never liked the Garmins because of their clumsy interface (the buttons placed above the display NEVER made sense to me) and how the menu structure was built.

However.... We're planning a 2000 mile road trip from Utah up to the Oregon coast. We needed something with expandable memory so we could upload more than one state map at a time. My wife bought me the Magellan eXplorist 600 for Fathers Day. I forced myself to use it for two days (and believe me, it was torture). I could go on and on about why I sent it back.
What I ordered as a replacement was the GPSMap 60Cx. Now keep in mind that I felt like someone who had turned to the dark side.
I couldn't be happier with my decision.

While I agree with most of the other reviews about the lack of base maps, and the expense of additional ones, this unit ROCKS! It acquires satellites within seconds. It has expandable memory. It has a color screen. It manages Geocaches. It auto-routes. It stores 1000 waypoints. It has SiRF Technology. It is a USB interface. It has a belt clip. It changes display contrast at night (automatically). It slices... It dices....
Suddenly the Dark Side isn't so dark!!

This is a great unit that I would recommend to anyone.

Most versatile of Garmin's Handheld GPS modelsAug 25, 2007
By L. G. CHARLOT
Among the plethora of handheld GPS models on the market, the 60CX probably offers the most all-around useful features.
What I like about the 60CX:
1. Very fast satellite acquisition thanks to the SirfStar-III chipset. Sitting indoors at my kitchen table and typing this review, my 60CX is tracking 8 satellites , including the WAAS satellite, and is showing the "location error" as only 22 feet. The 60CX also works remarkably well under tree canopy, inside my car, and in urban areas surrounded by tall buildings - all situations that would defeat most previous generations of handheld GPS's. The display processor has plenty of power, allowing speedy updates of the map even at tight zoom scales where the map is showing the maximum amount of detail and is changing rapidly if you are travelling at freeway speeds.

2. The Quad Helix antenna allows the unit to track satellites no matter what orientation the unit is placed in, horizontal, vertical, or face down: it still works. This allows the unit to be used on a belt clip, automobile or bicycle mount, or in a backpack pocket and you won't lose satellite lock. The patch antenna of units like the Garmin E-Trex or Lowrance IFinder models only works at full efficiency if the unit is placed horizontally on it's back, with the antenna facing upwards. For comparison, the E-Trex Legend I used to own would not track satellites if placed in a shirt pocket facing inwards, or if it got turned upside down on the dash of my car.

3. Connectivity and software. The 60CX comes with MapSource software, which allows upload/download of Waypoints, Track Logs, Routes, and Maps via the included USB cable. If you buy any of Garmin's optional cartography products like City Navigator or TOPO 2008, these maps all work together seamlessly in the same MapSource session. You can create or edit your routes and waypoints graphically against the map background on your PC screen, then upload the data to the GPS. Track logs recorded live by the GPS can be downloaded to MapSource, easily edited to remove "outliers" ("bad" track points caused by poor satellite PDOP), then uploaded back to the GPS. MapSource is pretty intuitive, user-friendly, and easy to learn.
While the 60CX is connected to a PC by the USB cable, it is being powered by your PC, saving the batteries in your GPS.
In addition to the USB connection, the 60CX has an RS-232 serial connection to allow it to communicate navigation commands to other devices, like marine autopilots, or chartplotting software like SeaClear or Fugawi Navigator, using the NMEA-183 Protocol. The serial connector is a 4-pin DIN socket that also allows the unit to be supplied with DC power from a vehicle or boat 12 volt electrical system. Garmin sells a cable with a 4-pin plug on one end, and the other end bare wires to connect to your accessories. This makes the 60CX a usable alternative to much more expensive dedicated Marine Chartplotters on your boat - it should connect to any marine autopilot that is NMEA-183 compatible. When you are not using your boat, the 60CX can be used in your car, as it does auto routing (if you own the optional City Navigator mapping product).

4. GPS Features. The 60CX is so packed with features, it's hard to think of anything else it could do that isn't already built in. It even has a display to calculate Glide Slope if you were using it in a sailplane. That said, keep in mind that the 60CX is a general purpose handheld unit, and while it has tons of features, dedicated Marine Chartplotters or Aviation GPS models will offer more capability for use specifically on boats or in aircraft, starting with a much larger display screen.

5. Build quality. The 60CX feels like it is sturdily built. The lower part of the housing is coated with knobby soft rubber right where most people would tend to hold it in hand, although increasing the area of the coating further up the sides would be nice. The latching mechanism on the battery compartment door uses metal instead of plastic for both the "male" and "female" components, which is good, but the effort required to turn the latch on my unit is higher than I would like, leaving me to wonder if the latch pin will eventually fail from metal fatigue. The micro-SD card lives under the batteries and is so tiny that changing it requires nimble fingers, at least more nimble than my "fat-sausage" fingers. If you've got an 8-year old kid handy, let him/her change your SD card. Or use a tweezers. The included belt clip seems to be well built, but I would recommend also attaching the GPS to one of your belt loops (assuming you're not wearing a skirt or dress) with the supplied wrist lanyard (or a longer cord for more reach). I have had the belt clip come off when getting into or out of a car, which would have caused the GPS to free-fall onto my concrete garage floor if I had not also used the lanyard.

The display is reasonably readable in direct sunlight, and very good indoors with the backlight on. The display is hardest to read when the ambient light is less than "full sun", but still too bright to use the backlight, for example outdoors on a heavily cloudy day, or in twilight like that first 1/2 hour after sunset. Although the above sounds like I rate the display as "poor", it is MUCH better than the display on the E-Trex Legend I used to own. I guess what I am trying to say is that I have seen sharper color displays on high-end PDA's, so the 60CX display might be a little disappointing to people who own such devices.

The most noteworthy features are:
(a) Ability to record your Active Track Log as a GPX file on the Micro-SD card, up to the memory limit of the card. A new GPX file is created each day (at 00:00 if the unit is powered on as midnight passes). These GPX files can be loaded into MapSource and edited as a tracklog, allowing multiple GPX files to be combined if you want. This feature means that the 10,000 point limit on the "active track log" could theoretically be worked around to record a much larger series of track logs at FULL precision. Lowrance IFinder models can also record track logs (trails) to micro-SD card, but Lowrance's track logs do not include Elevation or the time/date stamp on each track point like Garmin track logs do.
(b) Automatic generation of Routes for your road trips. This feature looks and works pretty much the same as on a Street Pilot or Nuvi, except the screen on the 60CX is smaller, and you don't have Voice commands telling you when to turn. This feature requires you to purchase extra-cost optional mapping like City Navigator, that includes all the "attributes" of the roads, like where and how they intersect, speed restrictions, one-way restrictions, etc. In auto-route mode, the 60CX does warn you of upcoming turns with big text messages and arrows, and it will automatically calculate alternative routing if you miss a turn. If you don't own City Navigator, the 60CX will let you manually create and store routes, or back-track a previously recorded tracklog, and the turn warnings will still operate.
(c) Route Profiling. If you have TOPO 2008 cartography (see my review on that product), the 60CX can generate and display the Profile of the roads along your route. This is nice for planning any kind of hiking, biking, or road trip.
(d) Topo Mapping (land) or BlueCharts (marine). These are extra-cost optional mapping products that allow your 60CX to display maps or charts that look a lot like USGS Quad Maps, or NOAA Marine Navigation Charts. Many other Garmin GPS's can also do this, it's just that the 60CX does it in a handheld package with lots of versatility to use it in your car, boat, RV, bicycle, or airplane, or even just walking around on your own two feet. The built-in basemap in the 60CX is pretty rough and includes only major highways, also the outlines of coastlines, rivers and lakes are mostly horribly inaccurate - the 60CX can't realistically be used as a marine chartplotter unless you buy an appropriate optional mapping product like TOPO 2008, BlueChart (for your region), or Inland Lakes. Check out Garmin's website for more details on what you actually get with their mapping products.

The rest of the 60CX's feature set is pretty much the typical features that you get on all Garmin or Lowrance IFinder handhelds, i.e. Waypoints, Routes, Tracks, Calendar, Sun and Moon set/rise times, etc. The 60CX also has some extra features specific to Geocaching, Marine Tide Stations, and Hunting and Fishing recommendations. For an exhaustive list of everything this GPS can do, go to Garmin's website and download the PDF of the complete owner's manual.

WHAT I DON'T LIKE ABOUT THE 60CX:
1. The map display shows land areas as a medium tan color, and I have not been able to find a way to lighten this color or change it to plain white. This tan color is too dark and offers insufficient contrast to overlaid features like city streets that are a brown or red color that is only a little darker.
Battery life is less than some other handheld GPS's, but this isn't really a complaint since the 60CX has a very powerful display processor. I also own a Lowrance IFinder GO, and while it has nearly double the battery life of the 60CX, it is a monochrome display and the processor is so underpowered that it is positively agonizing to plan a route using map pointing. The 60CX is light-years better than the IFinder GO, and if the price of all that power is only 16 hours of battery run time, it's worth it when you are actually using the unit for real-time chart plotting or route planning.

OVERALL SUMMARY: In my opinion, the 60CX is probably the best all-around handheld GPS from Garmin, offering the most comprehensive and versatile suite of features. Although it is not as capable for automobile routing as a dedicated Auto Navigation GPS like the Street Pilot, or as powerful for Marine Navigation as a full-fledged chartplotter, it can substitute for these devices if you can live with the small display screen and lack of some features specific to Marine or Auto Navigation. For hiking or bicycling trips, it is an excellent GPS that offers far more capability than the smaller wrist-mount GPS's (although at the cost of a little more weight and bulk). The ability of the Quad Helix antenna to allow satellite lock with the unit in a pocket or mounted vertically makes it preferable to any GPS with a patch antenna for hiking or backpacking, and probably better for mounting in a car or boat where you would probably mount it vertically. NOTE: for use on a yacht making a blue-water passage, I would recommend the 60CX as an emergency backup to your boat's regular chartplotter.
I rate the 60CX as Highly Recommended and I give it 5 stars with no reservations.

*******
UPDATE: June 9th, 2009:
My original 60CX is still going strong, except for one issue: the power button has started to get unreliable, sometimes requiring many presses before it "wakes up" and does it's job of turning the power and screen backlight on or off. Over the 22 months I have owned this unit, it has proven it's versatility and value many times over. I've used it for navigation on the road, in my boat, on hiking trips, and even at 35,000 feet on airplane trips. I recently added City Navigator NT 2009 and with it installed, the 60CX seems to do everything a Nuvi or Streetpilot can do except talk. The entire content of City Nav 2009 (that's all of the US and Canada!) can easily fit on a 2 gig microSD card with nearly a gigabyte left over for tracklogs or other maps. I have also started playing with "home made" maps, which can be compiled and uploaded to the 60CX's microSD card with several different suites of mapping programs, some commercial and others freeware.

*******
UPDATE: June 04, 2010
My old 60CX is still operational, the power button problem is still happening but remarkably not as severe as a year ago. It will usually power on with only 1 or 2 presses of the button. The price of the 60Cx on Amazon is down to $260, half what it was when this GPS was first introduced. More than ever, I feel the 60Cx is a fantastic handheld, and the best all-around value for the price. However, if a touchscreen is a "must-have" feature for you, the Garmin Oregon 450, at about $100 more, would be my first choice recommendation. Compared to the 60CX, it has a much larger, higher resolution touchscreen display, about the same battery life, and as far as I can tell from the specs, it supports almost all of the features the 60CX does, especially realtime backup of the tracklog to the MicroSD card, auto-routing (if City Nav maps are installed), and even Marine functions like Tide Prediction and NMEA-0183 interface.

NOTE: The latest firmware releases for the 60CX, version 3.9 and later, adds support for SDHC cards (presumeably up to 16 gigabytes), a big improvement over the original 60CX firmware, which was limited to a maximum 2 gig size SD card. The implication here is that you can now put multiple types of maps on your 60CX, HOWEVER, it turns out that the 60CX can only display one map layer at a time. So, even though you could theoretically put all of TOPO US 2008, Blue Charts for the entire US, and City Nav NT all on one 8 gig card, City Nav will default to being the "top" layer of mapping and will obscure any Topo or Blue Chart maps that happen to cover the same area. To enable/disable various map layers: from the Map screen, press Menu/Setup Map/ then scroll sideways to the Information tab, then press Menu again. You will now see a pull-down menu with various commands to turn on/off the various map layers.
If you own more than one Garmin map product, you can also split your maps up onto different microSD cards. For example, put your Blue Charts on a 1 gig card, City Nav on a 2 gig gard, and TOPO US 2008 on another 2 gig card, and swap them out as needed. There is a another reason to split up your map sets on different cards: As your mapset selection gets larger, the time required for Mapsource to compile and export the mapset grows exponentially. A really big (3.5 gigabyte) mapset that I tried to build, that would have had all of City Nav, and about half of Topo 2008, would have taken 12 hours to complete! A 500 megabyte mapset by comparison, can be compiled in about 20 minutes. So there's a pretty compelling reason to avoid selecting gargantuan mapsets in Mapsource. There is just enough room between the microSD card retainer and the batteries to store a second microSD card in the unit (just be careful not to drop and loose it when swapping batteries). So, for example, you could have City Nav on one for use in your car, and your Blue Charts and Topo Maps on the other card for use in hiking and boating trips.
