Is any other user of Nuvi 3790 experiencing spurious rebooting with this unit?
Mine likes to reboot every once in a while. Updated to latest ver 4.80 of SW - no difference.
Any help would be helpful.
I have the same problem with a Nuvi 2460. In my case the reboot always occurs within 30 seconds of setting a new destination. At first I thought it was an overheating issue, but it is now located directly in front of A/C outlet.
3790t has a similar problem.
After switch-on it ...too often...auto shutdowns and requires a restart.
The agent says it is operating normally therefore no need for a warranty claim.
But this is not "normal" in the general sense of the word.
On thing you can try is pressing the battery icon for 9-10 seconds. Then, you will have access to checksum and infos on battery life, etc. Perhaps you will find something helping you with your rebooting problems
I've tried every solution I can think of to solve this, save a hammer. My sat nam works fine when its on it's own battery, which doesn't last long, but as soon as its connected to any power source, which of course is how we use in in our cars, here we go with this looping. As this problem has been going on with various Garmin sat navs for at least 10 years now, you'd have thought they would have come up with a solution. Or perhaps it's deliberately inbuilt redundancy to make us buy a new one - or goto our phones! :
