Satellite tuner: Control
WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
If the optional satellite tuner equipment is in the vehicle and a separate Satellite Digital Audio Radio Service control unit installed, the AM/FM receiver in the headunit is code inactive. In this case the Satellite Digital Audio Radio Service is controlled via the Media Oriented System Transport bus by the headunit (radio/multi-audio system controller/Car Communication Computer/multimedia platform/Car Information Computer). For the case where no external Satellite Digital Audio Radio Service control unit is installed, the satellite tuner function is integrated into the headunit directly (starting 09/2009 possible).
