Hi I am a new X710 owner and new to site. Please bear with me if this is a dumb question. I had my 710 installed by a local stereo shop. I wanted them to hook up my steering wheel controls (2000 Grand Prix) to the 710 but the part didn't come in time so I have to go back to get that done. I have read that the parkbrake hack from the F series will work on the X series. I grounded the park brake lead only and of course I get the message that the park isn't connected properly. I know I am getting this as I haven't grounded the "mute" wire. My question is that if I ground the mute wire will this prevent my mute button on my steering wheel from working once the part is installed?
Cheers
