I just took delivery of a 2007 Audi A4 and it's fully loaded, nav and every option that you can think except the bluetooth or onstar. They didn't have one on the lot with bluetooth and I didn't want to order it because will take two months to get the car. My question is if anybody knows if the car is prewired for bluetooth and all I need is the module, BT antenna and the mic plus all othe obd programming? I took apart the cover where the mic it's suppose to go, by the sunroof switch and I can see two cables in there, one it's a 2 pin connector ( my guess wil be that the MIC will go there) and also there is another black connector that has 4 pin. Let me know, thanks a lot. I will try to attach two pictures with the connectors and if anyone can tell me what are those for will be great.
