Roger Blassberg 0 Posted October 23, 2013 I have a 1990's Blaupunkt Gamma radio/tape/CD (actually in my Passat B4)which is misbehaving, not surprisingly after nearly 20 years of service. The front/rear fader sends no signal to the rear door speakers. The speakers and the cables are ok, there is a response if I flash a 9V battery through the relevant cabling from the radio-speaker connector block. Any suggestions or a recommendation to a reliable Blaupunkt repairer in Herts or North London? Thanks RB Quote Share this post Link to post Share on other sites
