Hey there folks! First of all, im Stan from Dumfries in Scotland. Ive just purchased a 1998 Audi A3 1.8 20v T Sport 3door in red. Its completely standard...... Until today . . . My abysmal Concert head unit finally gave up the ghost (volume problem), and i had my old head unit (USB, Ipod etc etc) lying around, so set about fitting that. It fitted fine after purchasing the necessary fascia peices and wiring harness to enable the rear speakers, but now my remote central locking doesnt work. I gather this is normal when fitting an aftermarket head unit, but i cant remedy it! Now, i have tried searching but never found a definitive answer.... Please help! Thanks.
