Hello guys and gals. I know that I can change my basic (no Bluetooth) radio to a higher unit. My local dealer is telling me I can NOT do so. They say the harness for the mic and the rear view mirror will not work on my truck. They are telling me that my only choice for bluetooth is a mopar unit that they want 600 for. I believe they are being dishonest. I just wanted a quote to have them flash the truck if I made the swap.
