Hi John,

I've just been looking at the Autoleads website, and they have three different adapter kits for your 5-series model.

The only caveat is that you must not have the multi-function steering wheel in your car. If you do, then it looks like it's game over.

As others have suggested, you would be well advised to ask the advice of a good car audio shop. Alternatively, you could always call Autoleads on 01420 476 767, and ask to speak to their technical department. I am sure they would be able to give you some advice.

Andy.
