User Reviews about Garmin Colorado 400t Handheld GPS Unit with U.S. Topographic Preloaded Maps

There is plenty of info out there on this GPS. I'm only going to mention one thing and if you do not plan on connecting your GPS to a computer you can skip this review. If you go online and download the free Garmin BaseCamp software you will think you are getting a nice piece of software to plan your next trip outdoors. What they don't tell you is that the BaseCamp screen shots they show on the website and instruction manual are based on maps that must be purchased separately. Even though you just paid for a GPS with built in topo maps.

So if you pay the extra $100 for a GPS with built in topo maps like the 400t you will have to pay another $100 if you wish to make your GPS useful when connected to a computer. To my amazement Garmin customer support told me to return the GPS and buy a cheaper one then buy the map separately so I can view it both on my computer and GPS. -- Included Software Not As Advertised

This product has been great straight out of the box. Great for geocaching. Poor quality and customer service from Magellan drove me to Garmin, and I'm glad I made the switch. -- Satisfied customer

Unit works well and the rock n roller wheel is handy. While elk hunting in Arizona I set a waypoint at the truck, then entered the forest. Tried to navigate back to the truck, but the unit was sending me in the wrong direction. I navigated back on my own and the unit said the truck was 5.3 miles to the northeast. All other attempts to navigate back to a waypoint worked well, just this once it was inaccurate. The only other issue is that it eats AA batteries like crazy. Will have to investigate rechargeable batteries to correct this issue. -- Eats batteries!

Was very happy initially with the unit when it arrived but quickly found out that the included user manual is pretty much worthless. I tried to find any additional user information from Garmin and nothing in book form is currently available. I did find out about a company called Bennett Marine Video that has a DVD's for almost every GPS unit and one specifically for the Colorado 300 and 400 series GPS. Not sure exactly what it contains but it is the only aftermarket product that contains more info than what's in the user manual. Also have noticed some issues with accuracy on this unit initially while doing some geocaching with my son locally. Had problems getting the thing to stabilize and quit bouncing around. Also had some accuracy problems when using it while snowshoeing in the Collegiate Peaks Wilderness area in Colorado. It would not lock onto the trail I was supposed to be following and I ended up totally losing the trail. This was a bit more than an inconvience when you are hiking in 5 to 10 feet of snow and cannot see the trail. I have become more familiar with its features and have done some communicating with Garmin support, have uploaded the 24K Topo series maps and upgraded the operating system software to the the new beta version and it seems to be a little more accurate. Will be testing it out again in the Rockies in a few weeks and see if accuracy in the mountains has gotten better. I like many of the features, like being able to add or remove shortcuts from the main screen and only have the ones you really need displayed. The battery life is great with 2700ma NiMH batteries and I have not had any problems with viewing the display in bright sunlight. The backlight is also great in poor lighting conditions. I would highly recommend investing in a screen protector. It's cheap insurance and they are easily replaced. I did find out that the built in thermometer not very accurate displaying the ambient air temperature probably due to the insulating effect of the GPS body. The bottom line I guess the best way to learn about this beast is just keep playing with it until someone puts together a decent manual. Will update this review once I finish my next wilderness trek and see how the accuracy does with the new maps and updated software. -- Garmin Colorado 400t after a years use.
