I called a couple of stereo places and they weren't too encouraging about upgrading the BMW because of the computer.
Did it myself... super easy actually since everything is in the trunk... took about 2 hours.. see my previous post inquiring about the gas door rattle for more info.. any more quesitons, just let me know but don't get tricked into buying a bunch of harnesses or paying someone 300+ to do a very straightforward install for you
