Seems like a warranty issue. Back to the shop then. Or, if the user manual contains a contact address of the Customer Service department of the maker, contact them.
Things that aren't clear in your post:
- what other "everything else" on this GPS is (my GPS just is a GPS)
- what data you stored on that device (all I ever store on my GPS are a few favorite addresses)
