Hi again, I have a radar detector that I want to hardwire to my car. Only thing is in my last car I used the ignition wire on the radio vs using the ignition switch. That way its switched on.
Does audi have a similiar ignition wire? Im asking becuase I noticed that even after the car is off i can turn the radio on and off.
I would try the overconsole technique but im not certain if that has a switched power turn on lead.
