How do u reset tomtom go 910 - Tomtom XL 330 Car GPS Receiver

SOURCE: how to reset tom tom 910

the reset hole is hard to find... If you are looking at the back of the unit, it is in the upper right hand side of the liitle plastic protrusion at the top of the semi-circular opening above where you can see the exposed circuit board.

you have to hold the reset for at least 30 seconds. Get up free updates and back up your device

A hard reset is done by pushing a paperclip into the reset hole on the bottom.

Letting the battery run down will not fix it, so recharge it. I suspect your maps have become corrupted or at worst deleted. Reinstall your maps from the CD or by contacting TOMTOM and quoting your licence number for a download.
Leaving GPS in car subject to extreme heat will danage the card and often the maps. Gloveboxes are not exempt either as they often reach over 50C when car is left in the sun. ( assuming it is summer wherever you are)
