That is where I am stuck, I think it is a performance version because of the 3.6 and no navigation.
I went to the dealer and they gave me a part number that included the 5.1 system. They wanted $500. I looked at my unit and the part number on the unit comes up with not having the 5.1. GM warehouse has it for $315.
The dealer used the VIN number to find the part, could that be wrong? Should I use the part number from the unit?
The number on the unit # 22748623 (23103205)
The dealer gave me # 23103203
Also if I replace it does it require any Reprogramming? The dealer wanted $139 for that.
