Telematics upgrade for 2009 S550?
Is there an upgrade available for the telematics of a 2009 S550? If so, what are the upgrades compared to the original function? I've read there is a recently released DVD upgrade for the navigation system to update the maps used, but I am not referring to that upgrade. I may buy that DVD, but I am more interested in an upgrade for the telematics system that would allow bluetooth streaming of music. Thanks.
