So I just got a 2015 SE charger. The radio seems to be upgraded by the previous owner. But when I try to use the uconnect registration or anything in the apps it wont connect at all. I also cant upgrade the radio os since its on ver 14.25.5 and when I type the vin in online it still says there is a 5 inch screen in it. Is there anything I can do at all or am I SO? Thank you all!
