If, and this is a big if, the police actually wanted to spend any time on it, they could finger print it and your car. If they find your prints on the gps, then you might have a good chance.
The "home" thing might work too.

A buddy of mine programmed his "home" to the cop that lives around the corner from him. His theory was that they would then target his home (not sure why he arrived at that conclusion...). But it would have been funny if it had all worked out.
