ren1990 Posted October 21, 2018 Share Posted October 21, 2018 2005 B7 AUDI A4 avant 2.0tdi Hi my radio isn't working. I've removed the head unit and have located the permanent live wire (Blue/red). I understand the Audi uses a canbus system and as such theirs no switched live at the head unit. I intend to run a wire from a switched live fuse and connect it to the stereo. Which cable would I connect it to at the stereo end. would I connect it to the blue and red permanent live wire. Alternatively if anyone has a different option. I would even consider running the permanent live and just rely on switching the radio off after I've used it. Cheers Andy Quote Link to comment Share on other sites More sharing options...
