Hey,

I have a BMW Z4 and i need just listen music via Iphone, I have a FM transmitter but quality is really bad, I know that can do a retro-fitting that helps.. Any idea of a decent not very expensive CarAudio Shop ?

ebay depending on what bmw stereo you have I think it can either be really easy and cheap, or really complicated and expensive.

Hey thanks for your replay, seems to be a bit tricky to install, that is why i what to take it to a CarAudio shop

There ia a place in Lucerne that does all that stuff.
