Up for sale is an AUX IN retrofit cable for the BMW Z4. The one i am selling is for the E46 but is exactly the same cable as the one for the Z4,only cheaper. I never understood why bmw does this but anyhow.... Never used, accidentally the seller that sold me these sent me 1 extra which he never asked back and now i have 1 extra sitting in my garage. I am looking for 25,00£ + P&P
