Okay I have a question. I don't have a mute wire. And I can't see the DVD, I get sound but no video. Also the damn caution always comes up. Also the navi I can't seem to get all the options. Is this mute wire part of the issue. Also where can I find this brake wire thing. (By the way it's an Avic d3 going into a 07 Chrysler 300 with Boston premium sound.) thanks in advance
