This is my second Navigon Navi and was super happy with the predecessor, but since it was stolen, I was forced to put me a new one. In itself it is really great and reacts very fast but the shutdown, it depends on damn often and must then be reset. Added to this was yet but that was the car charger defective I could not change the Navi, since I had to rely on and the seller did not respond to my mail. I'll update the device times and see if the resolve so!
