I have done the hardwire as to all the threads have instructed. I moved the mute wire and grounded it. I also grounded the parking break wire. I grounded these together then I was able to ground them to the frame. Here is my issue I have lost some of my functions in Nav, phone functions etc. As soon as I connected the mute wire I lost these functions however the annoying notice that the parking brake lead is not connected properly stopped popping up. So this would tell me that there is a contact to ground. I need some help what have I done wrong or not doing properly.
I have an X710
thanks
