I just picked up an '08 R32 with factory nav. It also has the OEM ipod adapter in the armrest and OEM bluetooth installed. When I push CD on the headunit I get the CD1, CD2, etc. that corresponds to the playlists on the ipod. There is also and 'AUX' setting and when I select it I get nothing. Is this for another adapter that can be hooked up to the headunit? Or is there another input in the car hiding somewhere already?
I got an mfd2 media unit off eBay for £85, pccm I think it was, from Germany or Poland.....
It has an input for RCA connectors and a rear view camera, I then got a dual iPhone charger to USB plug and RCA outputs off eBay for £8.
Then wired a USB car charger socket off the rear of the cigarette lighter socket and placed it all out of site behind the aircon controls, I put a Brodit iPhone charger dock on the dash.
Simple sit the phone in the dock to control the iPod on the phones screen then press the AUX button and you get your music through all speakers and videos on your mfd2 screen.
