After replacing my radio I've noticed my MFD isn't working properly. When I try to adjust the a/cit says check a/c controls. it also dosent show my mpg anymore the screen isn't blank but no info is on there only should the tires spinning.
Did you install the 68Ω terminating resistor? Some interface wiring harnesses come with it, some don't. Search the Gen 2 forums (using the Advanced search option) to find the many posts that cover installing this resistor (if required).
