Query: It broke after 1 week

When it was working, the product was nice to use and fun to play with. Then, it broke. The arrow on the screen which is supposed to represent your position, stopped updating. I flew down to LA and was hoping to use it to navigate my way around town. Unfortunately, the unit didn't work there either. I contacted customer support when I got back home, and it's in the process of (hopefully) being repaired right now.
