I have a 2019 Ram 3500 Limited 4x4 with 12 inch panel. Nothing works anymore. No day time running lights, no lock controls , no towing controls, Nothing including the GPS. It will not activate. Have taken to the dealer and no one seems to know how to fix or reprogram the panel or system so it will operate again. I have been paying for the subscription and are thinking I will cancel and demand a refund if someone can not fix it.
