Can someone tell me what i need to install a aftermarket 1 din stereo so everything works? I currently have audi concert with subwoofer in the right side of the boot… (audi a4 b6 avant). Thanks for all the answers.
I am a new member so hi there. I own an A3 8PA, 2008 model. I recently installed an aftermarket HU, a JVC, replacing my Concert 3 (I think). Anyway, at this moment the aftermarket HU has to be manually turned on/off since that action won't be done with the help of the ignition.
