Garmin rebooting

If you do a reset you will lose your favorites and any settings you changed.You can hook your gps unit up to the computer and open up the Garmin folder.Click on Gpx folder (this is your favorites).Make copy of current.gpx and save it.After reset re-install it back but change the name to something else but keep the extension.

Hard re-set is done by holding two fingers on the bottom right of the gps screen while you power up the gps unit.

Note. Also check and make sure you don't have any duplicate files on the sd card. The first time or last one back maps were downloaded to sd card.Found two map sets on it.Deleted the old one.This time no problem with duplicates on sd card. Make a back up of your GPS files before you start playing around with map files.

Are you able to connect the Nuvi to your PC to see if the gmapprom.img and gmapbmap.img are present?

Have you tried a hard reset?

I had this issue with a 1490. I had tried the master reset, but it did not help. What did solve it was to restore my GPS back to it's "as received" condition. You did back it up didn't you?

First I used the old gupdate.gcd file to bring it back.

1) Save anything pertinent such as waypoints from the GPS to your computer.
2) Copy an old gupdate.gcd to overwrite the one on the GPS. (Be absolutely sure that the gcd file is for your model.)
3) Disconnect the GPS from your computer and turn the GPS back on. It will ask if you want to restore to an older version and in so it doing will delete anything you have saved such as waypoints. You will also have to reenter your preferential settings.

I then used my backup to overwrite any other files on the GPS.

After that I went to "Garmin Web Updater" to update the GPS to the latest version.

So far, its been a year or so and I haven't yet experienced random reboots. Obviously, somewhere along the way some file got corrupted.

Incidentally, I recently restored my 3590 using the same method. In this case, traffic reporting became virtually nonexistent. Again, a master reset did not solve it but a restore back to original configuration did.

Good luck!

I also had a similar issue with my 3490, I am driving and all of a sudden my Garmin starts rebooting. This has happen more than once and only since the recent software update seems to have corrected the problem

same thing happens to my 885 every so often.
