You will need the mounting kit 84110390240.
The tuner just bolts on. You will need to pull the headunit out and detach the connector that is taped to the harness with SDARS written on it. Swap it in to the radio connector for the audio and tape back the one you removed.
For the iPod, the BMW one should be avoided. For a start it won't fit the iPhone 5 and future iPhones, and second it does not support text, you get six playlists matched to the 6 CD buttons and that's it.
Look at a Dension or a DICE Mediabridge and plug it in to the CD changer sockets under the storage bin in the front armrest.
Thanks.. I got a unit from my local BMW dealer along with mounting kit. Installed it, and now getting error message "No Antenna"? Any suggestions? My X3 is sat ready, popped the HU off and switched to SDARS plug..
