Hi there, just bought a 2012 Chrysler voyager. Switched on the uconnect system, set the clock, changed sat nav to Uk as it was German. Next time I switched on, the clock had lost time, but the whole system was in German...no matter how I try to change it back to English in settings , doing this manually or with VR , it won't let me. Then the next time I get in the car, the clock is still wrong, but it's all back in English again ! I'M SO CONFUSED ! please someone help !! Cheers. Murdoch
