I had this problem too with the one I got from my sister. If you tap your finger in the lower right of the touch screen mine came back on. I think it resets the screen with commands that come back into the screen area. Try that and let me know. Dale.

SOURCE: Hello.I have a problem with my GPS

well it may have come with a CD that had the maps on You have to reintsall the maps. The mp3 Mp4 working has no relation to the maps excdpet that they often overwrite or corrupt maps.
if you dont have any backup maps you will hyave to buy new ones as they are not free nor under any warranty. what country are you from ?

SOURCE: Hello, when I turn my Invion GPS model:

Believe it! if it says maps not found putting it away for a few months wont repair it Ypu need to have the maps reinstalled. possible to corrupt maps easily by a spike from car charger or even leaving unit in a hot car or starting the engine while unit connected.
