If you have a built-in TomTom GPS in your car (Carminat – Renault), you might experience that the device reboots continuously after updating the SD Card with TomTom Home.
The device shows the startup screen, a black-and-white hourglass, and then the startup screen again, it continues endlessly.
Two actions might solve your issue:
- the support site of TomTom suggest you delete the mapsettings file. That did not solve the issue for me;
- mounting the SD card on a computer and deleting the loopdir folder in the root of the card solved the issue for me, as suggested here. Personally, deleting that folder did not delete my favorites, the only thing I had to do is set my home location again.
