I have a 2003 b6 with bose and im trying to fit an appradio.
I understand that to get power i should connect the red and yellow wires together however, the appradio can not be turned off so i cant do this.
My other option would be to tap off a fuse box feed, but i have no idea about this.
There are wires going to the oem stereo that send canbus signal is there no way i can use these.
Is there any other way to do this?
