Hi All
Looking for a wiring diagram of the existing stereo connection for a 318TI as I am wanting to fit a Sony unit. I have searched everywhere with no luck. I found an E36 Coupe but it is not the same. All I want to do is marry up the existing wiring with the Sony unit. Has anyone else had the same problem???? Frustrated

If you have the original 17-pins connector all you need is a BMW-to-Din adapter cable.
