I recently bought a 91 100Q with the Audi/bose system (yes, I beleive I will Have to replace the amp'd rear speakers), and installed a new battery. Unfortunately, the stereo went into theft mode, and although I do know my code, I can't figure out how to administer it. The owners manual is of no help here, so I turn to all of you. Thanx.
