Miscellaneous
M1.) Are there any diagnostic modes? How do I get there?
Yes. Press the center button of the Rock'n Roller and hold it down while powering the GPS on. You'll enter a debug test mode that will give internal data and test screens, including a hard button test screen. To access these test screens, press any of the two hard buttons while in debug mode.
Another diagnostic mode is available through the Trip Computer Tool. First select Others->Trip Computer->Options->Recreational Mode. On the Rock'n Roller hit up, right, down and left quickly. You'll end up in a diagnostic screen that shows the most recent Shutdown reasons. Options->Show Stacks shows some memory usage, probably of tasks running on the Colorado. There is some information on the memory heap near the bottom of the screen. Options->Go To Test Page will get you to the power on diagnostic screen above.
M2.) Can I get screen shots of my Colorado in action?
Yes. Press and hold the right soft key for about 5 seconds when you are viewing a screen that you would like to capture. If you have tones enabled you will hear a confirmation beep when the capture has completed. Connect your Colorado to you computer and the screen shot should be saved in [drive]:\Garmin\scrn\.bmp .
M3.) Can I change the background image on my Colorado?
Yes. Connect the Garmin to your computer and copy a .jpg file into [drive]:\Garmin\Profiles. Disconnect, power on the Colorado, select Shortcut->Setup->Display->Background and select the file you just downloaded. Only jpg's work. Any size photo will be resized but the optimal resolution for the Colorado screen is 240x400 (w x h) pixels .
M4.) Is there any way to make the screen of my Colorado easier to read?
Yes. Loading an all white background image improves screen readability. An all white 240x400 jpg image is linked below. Follow the instructions in M3 to load this image as your background. Tip: Use an image editor to add your name and contact information on top of the white image if desired.

M5.) What types of image files does the Image Viewer support? Where do I put images in order to see them in the Image Viewer?
The Image Viewer only supports jpeg image files and these files can be located either on the internal drive or SD card. You can place them in any directory except for [drive]:\Garmin\Profiles. Images put in that directory are ignored by the Image Viewer and are useful only as background images.
M6.) Can you navigate from an origin other than your current location? Does the Colorado have a simulation mode?
Yes to both questions. The Colorado has a simulation mode which is useful for trip planning. Follow these steps:
- Where To and find the new starting point you want to use.
- Once you have selected your new starting point enter Go
- Others->Satellite->Options->Use with GPS Off
- Answer "No" if you are asked whether you want to simulate the driving route.
- Others->Satellite->Options->Select Location on Map
- Pan the map to the destination you selected in step 2. This will be your new starting point. Hit enter.
- Where To and select your destination
- Optionally, you can decide if you want to simulate driving this route. Simulating is very slow, so if it is a long trip I wouldn't recommend it.
M7.) Can I force the Colorado into AutoLocate mode?
Yes. Follow these steps:
- Others->Satellite->Options->Use with GPS Off
- Options->Use with GPS On
- Options->AutoLocate Position
Steps 1 and 2 are necessary in order to get the CO into Acquiring mode. Once in Acquiring mode you need to do the third step quickly before the Colorado gains satellite lock. The AutoLocate Position menu option only appears if the unit is not locked. Sometimes the CO gets lock so quickly you may need to move to a location with no reception.
M8.) What is the little red dot on the Satellite page?
If you are in North Up mode on the Satellite page (Satellite->Options->North Up/Track Up) the red dot indicates your current direction of travel. If you are in Track Up mode your direction of travel will be the top of the satellite (horizon) circle and the cardinal letters will move as your direction changes.
M9.) Why is there a big red "X" through the GPS signal strength meter on the summary page?
You have the unit in GPS Simulation mode. The most common reason this happens is the unit was trying to acquire satellite lock and could not. When you were asked if you wanted to continue to search for satellites you replied "No". To get the CO out of simulation mode select Others->Satellite->Options->Use with GPS On or power cycle.
M10.) What are all the files in [drive]:\Garmin\Profiles ?
The .jpg files are the files which the Colorado can set as your background image. The .gpf files are XML-based profile descriptions, they contain configuration information for all of the various configurable settings on the Colorado and how they are set for each profile. Presumably the Colorado reads these files when you change your profile to modify the settings.
M11.) How do I master reset my Colorado?
Warning: This procedure will delete information (waypoints, routes, tracks, etc) from your GPS and settings may be set back to factory defaults.
1. Power the unit OFF
2. Hold down the two Soft Keys for 2 seconds
3. While continuing to hold the 2 Soft Keys down, press and hold down the Power button for an additional 5 seconds
4. Release all buttons, and select YES to the prompt asking "if you want to clear all user data?"
This form of reset does not seem to reset all of the settings to factory defaults, just a few of the basics like Time Zone and Language, the remainder of the settings are still taken from your existing profile files.
Once you have completed a reset remember to place the Colorado outside in a stationary position for 20 minutes in plain view of the sky so that it can rebuild the almanac before using it again.
Note: Holding down both soft keys and the select button in a similar fashion seems to do a similar reset to the Colorado. This may be a master reset that will also reset the profiles back to the default -- needs further testing.
M12.) My Colorado seems to be corrupted, is there a way I can recover it?
Warning: This procedure may delete information (waypoints, routes, tracks, etc) from your GPS and settings may be set back to factory defaults.
If you can't get your CO to start properly and it will not go into USB storage mode when connected to your computer you can try this as a last ditch recovery. It worked on a 400t that would freeze when loading maps and soft/hard resets didn't not work, I've also used it to recover a Colorado which refused to boot because of a bad gpx file.
First you'll also need to download file below. Once you've downloaded this file unzip it into a directory such as C:\Garmin on your PC.
On your PC click the Start menu, select "Run..." and type "cmd" where it says open. A black window with a DOS command prompt should appear. At the command prompt enter the following command:
> cd c:\Garmin
At the next command prompt type the following command without hitting enter:
> Updater.exe 066101000230.rgn
Now back to your GPS.
Press and hold the "up button" on the Rock'n Roller while you plug the CO into the USB cable. Wait 10-20 seconds while still holding the "up button". You should see a Garmin banner and nothing else. At this point you can hit enter on your PC to execute the updater command. Once the updater runs you will need to select youy Colorado under USB and hit enter. This should perform the update to firmware version 2.30 (you may get a warning about loading an older version of software). You should receive a message that the update was successful and the Colorado will reboot.
Once the reboot is complete the "Loader" banner should appear near the top of the CO screen after about 30 seconds. Release the "up button" and on your PC you should be able to see the Colorado as a USB drive.
Now is the time to update the Colorado to the desired
firmware level.
You can now attempt to fix the files on your Colorado which are preventing it from starting. If you've recently added or changed files these are good places to start. Deleting gpx files and/or replacing map img files with your backup copies may resolve the issue as well.

M13.) Can I assign a special name and symbol to the drive associated with the Colorado GPSr and SD card in Windows Explorer?
Yes. You have to copy the file called Garmintriangletm.ico from [drive]:\Garmin into [SD drive]:\Garmin and copy autorun.inf from [drive]:\ to [SD drive]:\. The next time you connect to your PC the SD memory card drive will have the same symbol (i.e. blue Garmin triangle) and name as the internal memory drive in Windows Explorer. To assign a different name to the SD memory card drive edit the autorun.inf and change the text after "label=". (e.g. label=Garmin Colorado SD Card).
If you prefer something a little more exciting than the original Garmin triangle
icon, try one of these:
