Once again I would like to thank you guys for the advise on my last thread (looking for a busniess cd for an E65). My 2002 E65 is good to go, being that I let the dealer do what they are known for. It cost me a pretty penny, but the car is working like its suppose to. In my last thread I stated that my car had Aftermarket: Tv's, Dvd, Cd changer, Ipod Video, a rear camara, and a custom system. All these toys are no longer operable being that I had to remove the aftermarket radio and put back the original Cd player that came with the car. Due to the fact that I began to experience alot of programing issues. A suggestion was made that a nav. audio/video interface will solve my problem. I am reaching out to all you knowledgeable guys for advise in what would be the best thing to do in my situation. This car has over 10gs of work into it and I would hate to loose out, but I want my cake and I would love to eat it to. I work hard so it's only right to play hard.
