Tyre totravel files corrupting Garmin 3790?

Not sure if this is the right spot.

Have a Garmin 3790 and it appears as if after loading a Tyre route from Basecamp (not direct from Tyre) it now won't boot up. It is stuck in a re-start loop, starting to load maps and then quits and re-starts on it's own repeating the cycle over and over.

Anybody have had the same experience? And found a way to fix it?

You could try this:

nuvi 37xx series hard reset:

1. Power off the unit (press/hold the power button for ~7 seconds)
2. Power on the unit
3. When the Garmin copyright screen is displayed, press & hold the bottom-right corner of the screen
4. Release the screen when "Do you really want to erase all user data?" appears
5. Touch "Yes"

Alternate method:
1. With the unit powered on at the map screen, press the bottom-right "Speed" field which will take you to the Trip Computer page
2. Press/hold the area just above the numerical speed on the round speedometer dial (where the compass heading is displayed when moving)
3. After pressing this spot for ~7 seconds, you will enter diagnostics mode
4. Select the first option displayed "Clear all user data", then follow the prompts

Reset all your location settings and user preferences. Also restore your favorites using the method outlined at the beginning of this post.

If possible after the hard reset (all units), let the unit sit outdoors in the open for about 30 minutes or so to let the unit re-acquire satellite almanac data.

At least you will get a functioning unit back and can investigate after that.

Good luck.

Rick,

thanks for your detailed instructions. I will keep them. Fortunately I could re-connect on my PC and after another system and map update by Garmin it came back to life. Let's hope it stays that way. So I think has nothing to do with Tyre, just coincidence I hope.

I had my TomTom hang up when I down loaded too many POI's. My Garmin NAvigtor I hangs up from radar occasionally. I have to remove all power, including the replaceable batteries. One time by a Radar site near Trona, Ca. Again coming down the mountains on Sunday. Just froze up.
