Hello everyone, Noob to this site. as you can see by my first post.
Been looking all over this site for someone who might of ran into my same problem.
I did my by-pass by cutting a piece of the brake wire and adding it in the slot next to the mute wire. I grounded it in the same location with the parking brake and the normal black ground. But everytime I turn the radio on it is muted. and I have ATT showing on the right and its grayed out. Once I remove the by-pass wire the radio works fine.
I followed the picture on Post one and there is also a video on youtube. The by-pass works
