Summary: what can I say, it is good when I received it, but broken one week later. my bad luck. it was usable when I receive it, and only thing I felt not good was the battery life was short, about twenty minutes, but with the car charger I don't think it is a big p;roblem. but now it is broken, I did not knock it at any place, it just broken for no reason.
Pros: Still better than Tom Tom (not going with NAVTEQ really shows), Touch Screen, Reliable - Lots of satellites/good signal
Cons: Slow Re-routing, slow to process through menus/features, Nighttime view is still too bright, Phone conversations via Bluetooth are not loud enough at full volume/digitized TTS is 2x louder at half vol
