Has anyone replaced their OEM radio with an aftermarket with bluetooth and still use the steering wheel controls. What brand did you use and did it allow for cell phone and ipod use through the speaker system. Just asking about a 2007 A4.

 

I'm looking into changing out my Symphony II on 08 avant and was told by the local stereo shop there is a module that allows this function to be continued on at least some aftermarket radios (I'm looking at ones with GPS, Bluetooth, and Sirius). They said they need about a week to order and get it in, and it was something like $100. Good luck.
