Hi guy's, just joined and I know this topic has been gone over before..but I didn't have time to browse and find it (sorry). Bought an 11 edge last year and the radio went out 2 weeks ago. Took it to the dealer and they said the APIM was bad and it would be $1200 for reprogramming and installation. Can I put a pioneer 7 inch touchscreen in its place? I know there will be a special harness I will have to get,but I just can't see paying 1200 to have that done. Thanks for any help.
