240x400 Screen - "Rocker" - MTK GPS - SD Card - AA Batteries
Latest versions : Main Software/v3.30 - GPS Firmware/v2.90

Product page on Garmin's site : >> link <<

UPDARTED 20100406 - Software v3.30 released for BirdsEye compatibility

UPDATED 20090922 - Software v3.00 and GPS Firmware v2.90 are available via the Webupdater.
UPDATED 20081015 - GPS Firmware v2.80 version available via the Webupdater.

UPDATED 20080409 : new v2.51 beta software available, see detail on page 6.

UPDATED 20080313 : A test unit has just arrived in the "GpsPasSion Labs" and first impressions are good. The map rendering is particularly impressive compared to the 60CSx, both in terms of speed and color. The "Rocker" is easy to get used to and more convenient than it seemed at first sight. The only concern is for the battery life that is well below the rated 15 hours. More comments and comparative pictures >> HERE << on page 5 and make sure you check out this excellent Colorado FAQ by g.o.cashers too.

Posted 20071209 - Looks like Garmin is working on a new "space age" handheld receiver !

Planned release date is purported to be the spring of 2008 according to mainesailor on gpsinformation : "I have had my hands on one of the prototypes, should be released spring '08. The large round button allows quick navigation to various functions from each page activated from options button on top right of unit (as you look at it.....opens a "window" on screen). Nice form factor overall, easy one handed operation and fast processor.

I work in a marine store and all the Garmin reps have 'em in hand to evaluate.

Nice unit, retail will be in the $500 + range, street price remains to be seen."

You can make your own raster maps for the Colorado, Oregon and Dakota now : Garmin's Guide for "Custom Raster Maps" and the tool is...Google Earth !

Anyone know why I can't get my queries to show up on the Colorado 300. When you look in the folder, they are there but when I choose the Geocaching feature, nothing shows up. I get a "no matches found" message. Thanks.
gpspassion Posted - 27 mai 2009 : 11:15:45
You can now customize the startup and other screens of the Colorado ->
gpspassion Posted - 28 mars 2009 : 18:58:07
The Garmin mount would certainly be a good choice, here are other alternatives ->

Does anyone know of a good window/beanbag/dashboard mount? I have been looking about and have found only one or two (mainly the auto kit from Garmin). I use mine a lot in the car and would LOVE to not have to hold it while driving!! Thanks!!

It isn't as bright as some of the lower resolution devices out there but you get used to it.

As for battery life you can get at least 10-12 hours on a set of NiMH 2700mAh batteries, more if you are careful with the backlight, turn off the compass, etc. Battery life comparison of the 60csx, OR, and CO here.

Hi, I have seen this unit, the 300 around for about 175$ now AR. I am concerned with what others have said about the BRIGHTNESS and BATTERY LIFE. Is it now up to par, and will it get a full day on rechargers?

How does it compare hardware wise to the 400? for the money, I don't think I would go up to the next CLASS of device for another 200$+
g.o.cashers Posted - 09 déc. 2008 : 00:36:44
Firmware 2.9 now available for the Colorado:

Changes made from version 2.80 to 2.90:

* Added support for Garmin GB Discoverer maps
* Added ability to view marine chart notes for marine points
* Added ability to change the date for the tide and currents charts
* Added support for marine fishing, nautical, and off modes
* Fixed a potential shutdown that can occur when panning the map that is showing satellite imagery
* Fixed issue with 3d view not showing proper elevation detail

Looks like Garmin is trying get GB Discoverer map support in the OR and CO so they can release that product!

After two weeks of testing on the Colorado I've seen one "drift" which was about 150' and shorter than I would have seen with GPS Software 2.6. I believe Garmin has made some significant improvements but it might the location errors might not be 100% eliminated. Note the Oregon did something very similar on a different test.

gpspassion Posted - 19 oct. 2008 : 20:43:44
Thanks, looking pretty good indeed! I must admit I have switched to the Oregon with its handy touchscreen and don't see any reason to come back to the Colorado at this point.
g.o.cashers Posted - 19 oct. 2008 : 15:18:10

Here are several. The first two are with just Colorado (blue) against the 6m-7m wide reference track. The last one includes the Oregon (green), 60csx (red) and the Colorado (blue) against the same reference on a different day.

In all cases the Colorado did very well and I have another from yesterday which was also good, certainly no major drifts. I'll continue to test over the next few weeks but so far so good.

gpspassion Posted - 19 oct. 2008 : 12:25:23
Thanks for the update, have you posted the new tracks on your "test course" ? Couldn't see any version numbers in the .rgn either.
g.o.cashers Posted - 19 oct. 2008 : 00:08:44
The new GPS 2.8 firmware does seem to fix the Colorado location errors. I've run 4-5 tests with the new firmware and the Colorado has done as good or better than the 60csx each time, something I did not see with the previous GPS firmware.
