Note:
Backpacking Light has not field tested the Colorado 400t. This brief show release is based on Backpacking Lightâs initial impression with the Colorado 400t on the floor of the Outdoor Retailer show and discussions with the manufacturer. The features and performance are as reported by the manufacturer and have not been verified. The initial releases of complex electronics equipment from many manufactures can be prone to early bugs and glitches. Many problems with these rather complex devices don’t appear until you have had the device in the field for a number of days. Backpacking Light will obtain a Colorado 400t for review in the near future and begin formal lab and field-testing to verify the performance of the GPS.
At summer Outdoor Retailer 2007 we reported in Electronic Mapping Comes of Age for Handheld GPS on a new breed of GPS units that included downloadable 1:24k topographic map coverage of the whole US and satellite imagery overlays.
These new GPS units by Magellan and Delorme signaled a strong challenge to Garmin, the current leader in mapping handheld GPS. Since the Winter OR the Earthmate has been available for a few months and BPL is currently reviewing it. The Magellan Triton units are still a month or two away from market and the availability of test units.
Now itâs Garminâs turn. They debuted the new Colorado 400t at the Consumer Electronics Show a few weeks ago. We had a chance to play with a Colorado 400t on the floor of Outdoor Retailer. On the show floor one of the Coloradoâs best features is a new high resolution TFT display: at 400 x 180 pixels it is larger than quarter VGA. The Coloradoâs display is the largest, and highest resolution display weâve seen so far on a handheld GPS. And the Colorado doesnât just display topographic lines: it also does shaded topographic maps and even 3D terrain rendering. The Colorado also features a built-in electronic compass, altimeter and barometer, and ANT wireless.
With a display the size of the Colorado 400t, navigating with GPS internal topographic maps starts to make sense. And the Colorado has a higher resolution and larger display (almost twice the area) than the Delorme Earthmate and Magellan 400/500 handheld units, as shown in the table below. You get over twice the display resolution of older Garmin units like the GPS Map and eTrex series. Even with the larger display, the Colorado series is slightly smaller and lighter than the previous Garmin GPS Map units.
| GPS Unit | Oz | Display | Pixels | Dimensions |
| Garmin Colorado 400t | 7.3 | 2.6 x 1.5 | 400 x 240 | 5.7 x 2.4 x 1.4 |
| Garmin GPSMAP 76CSx GPS Â Â | Â 7.6 Â | 2.2 x 1.5 | 240 x 180 | 6.2 x 2.7 x 1.4 |
| Garmin eTrex Vista HCx | 5.6 | 1.7 x 1.3 | 240 x 180 | 4.2 x 2.2 x 1.2 |
| Magellan Triton 400 | 6.x | 1.7 x 1.3 | 320x 240 | n/a |
| Delorme Earthmate PN-20 | 7.0 | 1.7 x 1.3 | 220 x 176 | 5.3 x 2.4 x 1.5 |

The Colorado 400t comes pre-loaded with full set of US topographic maps, the same maps as the Garmin âMapSource Topo U.S. 2008â product. So for the computer challenged, or those of you who donât want to spend the time screwing around with your GPS, you can walk out the door and navigate anywhere in the US without ever downloading a map. It is not clear if the actual MapSource Topo U.S. 2008 computer based software is also included.
The pre-loaded maps on the Colorado 400t are âDigital topographic maps, comparable to 1:100K scale USGS mapsâ and not 1:24K resolution. Notch one up for Magellean and Delorme and their full 1:24K coverage of the US (but not free or pre-loaded). Still, you can load MapSource US TOPO 24K, National Parks, East and West topographic maps into the Colorado for most of the national parks and surrounding areas. And after a couple of years navigating with 1:100K internal GPS maps I find they work well for most navigation (provided you also have a 1:24K paper map set, which you should have with you anyway).
To aid navigation the Colorado projects 3D, shaded renditions of topography (but with low resolution contours). This is a welcome addition for understanding your route, especially if you are not adept at conceptualizing 3D terrain from topographic lines. Hopefully the 3D rendering doesnât crash the GPS. Every 3D rendering Iâve tried on my home computers has ended in the Blue Screen of Death. It would be nice if it worked somewhere, especially the field where itâs most useful.

The Colorado 400t uses a high-sensitivity GPS receiver. Wile we have not tested the Colorado 400âs receiver, previous high sensitivity Garmin receivers have performed quite well. For more on this see our review of the Garmin eTrex Vist HCx Garmin eTrex Vista HCx GPS Review.
The Colorado uses a new input device, the âRock ân Rollerâ input wheel, shown below. Similar to the ease of the input of the Ipod click wheel, the Rock ân Roller wheel zooms in and out on maps by rotating right or left. Press a button and the Rock ân Roller wheel also scrolls rapidly between screens and applications. We found the Rock ân Roller to be fast, easy and effective. Our only question is how well Rock ân Roller would work with a protective plastic cover over the GPS (for salt water, wet and muddy environments, or other high abuse areas).
The new Colorado âRock ân Rollerâ input wheel at the top of the unit.
Unlike the Garmin marine units (e.g. the GPS Map 76), the Colorado does not float. Even so, the Colorado 400c (when loaded with coastal nautical charts) and 400i (when loaded with inland waters nautical charts) will likely replace many Garmin marine units. Note: the GPS Map 76 button inputs work exceptionally well inside a waterproof protective case. I will be very interested to see how well the Colorado 400c works un-protected in the harsh environments (assuming the Rock ân Roller wheel prevents the use of a protective case).
Other Features
The Colorado 400t is optimized to do both geocaching and a newer version, WherigoTM. âWhereigo is the newest GPS-based activity from Groundspeak, the people who made geocaching a worldwide phenomenon.â With Colorado 400t you can wirelessly share your waypoints, tracks, routes and geocaches with other Colorado users. The ANT wireless in the Colorado could also be used to connect to a variety of peripheral units like foot pods, bike sensors, etc.
Finally, the Colorado now uses the ubiquitous full-sized SD card. (The eTrex and GPS Map series used the much less popular micro-SD cards).
About GPS Weight
GPS manufacturers continue to focus their innovation and marketing in two areas:
- Large-screened mapping units with full navigational functions [eg. the Garmin GPSMAP 60, 76, and Colorado series] around 7 to 8 oz, and
- Small âperformance measurement GPSâ, usually wearable, but with small screens, no mapping capabilities and minimal navigational functions [Suunto X9i, Garmin Fore Runner 205, 305; 405 and Edge 205 and 305] around 3 oz
As long as this trend continues, the most sophisticated navigationally capable GPS units with large useful screens are gong to weigh 7 oz or more. I donât see this changing any time soon. Your options for a lighter navigationally capable GPS are something like a mapping eTrex unit with a much smaller screen and only 1.3 ounces lighter, a basic 3-ounce navigational unit like the Gekko 301 (as long as they remain on the market) or the new Garmin eTrex-H unit (which may replace the Gekko).
We see no reason GPS manufactures can’t put a 2.2 inch diagonal (or larger) one-quarter VGA screen on compact 3-4 ounce GPS, but at this point they choose not to.
