The SOS light went on and the dealer said there was a problem with the satellite receiver in the car. They had the car for three days and mucked around with no luck. Now they say they have ordered a new 'panel' from Germany and also will have to replace the rear 'windshield' window since the antenna has a problem. Does this make sense? It is hard to believe that both the electronic panel and the antenna are broken at the same time unless they managed to break it all! Any suggestions on how to handle this or if you have had a similar problem. They say they will need the car for 2 more days! Sheesh!
