Garmin Colorado 400t review


UPDATE: I’m recommending the new touch-screen Garmin Oregon 400t instead of the Colorado. It has a superior interface, along with almost all the other good things found on the Colorado.

UPDATE 2: This model has been discontinued. For more current recommendations, please refer to our handheld GPS buyers guide or our Garmin handheld GPS comparison chart.

The Garmin Colorado 400t is one of the first in a new line of handheld GPS receivers from Garmin. With an entirely new interface, it is very different from the eTrex and 60/76 series units.

Before we get into the details of the review, lets compare the major differences between the four Colorado models:

  • 300 – Worldwide basemap with shaded relief, no pre-loaded detail maps
  • 400t – Worldwide basemap with shaded relief, U.S. topo maps pre-loaded
  • 400i – Worldwide basemap with satellite imagery, U.S. inland lakes and navigable rivers charts pre-loaded
  • 400c – Worldwide basemap with satellite imagery, U.S. coastal waters and Bahamas charts pre-loaded

Since this is a landlubbers blog, I’ll ignore the marine units. So the key question is whether to buy the Colorado 300 or the 400t. The 400t is a great unit for those who don’t already own Garmin’s Topo U.S. 2008, since it comes with those maps pre-loaded. Otherwise, buy the 300 and save some money.

I covered the Colorado pretty thoroughly in my hands-on Garmin Colorado 300 review, so I won’t repeat all those details and screen shots here. I highly recommend checking it out for a thorough look at the unit’s pros and cons.

  1. Now in no way do I want to bad mouth the Colorado series. Though I am curious if anyone else has had issues in relation to battery longetivity. I have had to contact Garmin on a couple occassions because batteries are only lasting a couple hoursafter a couple small quick fix system updates, still having same problem. I like the unit though battery issue could be a problem.

  2. Hi, thanks for your information. Its really useful for my handheld gps blog
