How do i reset my garmin colorado 300

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 you Colorado under USB and hit enter. This should perform the update (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.

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.

You need to select all the segments at the same time and then transfer to the GPSr. Do not send one set, then another as the second set will overwrite the first set.
