Hi there. I am desperately hoping someone is able to anwser this question. I fitted a aftermarket radio to the wifes A3 (well have you seen the price for an audi one!) nice and easy however it was storing the programmed memories. not a problem just the content power source wasn't working obviously only the key one. anyway long story which ends in me "shorting" something trine to find the constant feed. i heard something go pop. I though fuse however i have take the fuse out and it is fine. Any ideas? The only fuses I am aware of are in the right hand side of the dash (you have to open the door to it) Anyway I am hoping someone will be able to help, i am desperate and in the dog house with the wife, apparently some functionality was better then none!
