SOURCE: Nuvi 350 System Software Missing

Try this: Hold the power buuton down, you will see on the lower screen the word "Pre Booting - ". Keep holding the power button for about 60 second, then you will see on the lower screen "Booting".
This time, release power button; system will reboot and loading map... again.
I got the same problem, after research on the web. Nick 99990_0 had post this solution on (his Nuvi 660) but it work for my Nuvi 350 too. Good luck.

SOURCE: Garmin GPSMap 60 CSx USB Connection

Actually, I just solved the problem myself...

I went to Garmin's driver download site (http://www8.garmin.com/support/download_details.jsp?id=591) and got the latest USB driver (2.2.1) for the 60C. (Although, it appears that that driver pertains to all Garmin products, not just the GPSmap series or the 60C.) Installation instructions are pretty much standard for Windows drivers, so it's easy.

That: a) Garmin requires special USB drivers for their product is finicky (most USB-connectable products just connect automatically using Windows' generic USB driver), and b) my unit -- which had always worked just fine, and suddenly stopped connecting out of the blue -- remains a mystery. Nonetheless, a driver upgrade was the final step that I needed. (Although, I also swapped USB cables and upgraded MapSource, too, so maybe it's some combination of those things.)

SOURCE: Problem connecting Garmin nuvi 205 w to pc

Check your cable.

I had to switch to device to pc cable from the garmin original cable to a pc cable that works with my motorola razor. The funny thing is I originally tried the motorola cable and it wouldn't work, brought the garmin cable and now it doesn't work but the motorola cable does.

Now my pc finds the device and I can go on to the garmin site and update.

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.

Garmin gps powers off even when fully charged


If you're "recharging" via the car charger - you might want to try charging via USB jack on your computer - or AC adapter (if your GPS shipped with one) for 5 or more hours.

Many Garmin units develop this condition when used strictly in the car / cigar outlet power source. While connected to your computer, you should go to Garmin's website and download, install & run the "webupdater" software. When complete, your Garmin GPS will have the latest firmware and patches to the software (not maps!).

After charging via USB or AC adapter, your GPS should stay on. If your GPS turns on via a slide switch on the top, Slide the switch from OFF and hold in the ON position for 10 seconds before letting go of the switch. This should force a "boot" on the GPS.

If you're unable to get the device to power up, contact Garmin Support to determine if your device is affected by a a recent battery recall or if there are other suggestions they have to solve the problem.

I hope this helps!

I turn my Colorado 300 on, it starts, but dies while loading maps. Like the batteries were out, but they are new.


Hi, It seems to be backup battery on PCB. You have to replace it. It is very frequent defect for CO which was made, same battery there were used by Garmin was defect - shorter life time. Jean

Hi, if USB connection is OK, you have to make hard reset after that download firmware 3.40 by Uploader (no Garmin WebUploader). Your Co will startup but your data will be lost. Jean
