Don't get me wrong. I love my 2004 645ci. It's been absolutely bulletproof and a joy to drive. Well, there was that engine replacement at 18,000 miles and oh yeah, the power steering hose fell off the pump while driving it. Now that was exciting!
But my real question has to do with aftermarket goodies. I want to upgrade the audio/dvd et al so I can use blue tooth, mp3's etc. An upgraded map disc is over $200. Yikes. I have been all over the internet with no luck finding any kind of audio upgrade. Frankly there is very little after market for this model/car. I've heard rummors that the innards are almost identical to a 2004 5series? My local dealer won't even discuss aftermarket or much of anything else. Any help out there?
