I recently purchased an '00 528i with the standard audio system and would like to upgrade to the factory DSP system. From what I have read, the non DSP labelled head unit should be compatable after the connection of the coax cable to the proper amp.
What I would like to know from those more knowledgeable that myself is if this is in fact true, what the BMW part number of the amp is and about how much it will set me back. I do realize that the premium system has a subwoofer, but I would imagine that this could be added as well. Has anyone performed this conversion?
Most of the ports I have read are from owners upgrade FROM an existing DSP system.
