I have searched everywhere on here and have found nothing. All the instructions say to move the mute wire to the empty hole above it. Neither of the harnesses that plug into the back of the Z2 have any empty holes!!! I grounded the ebrake wire and i get a message saying it was connected improperly is it supposed to say that? Any ideas guys? Also i burned the disc with the update files and i put it in and hit MAP but says nothing about UPDATE.

There are three harnesses so make sure you are looking at the right one, the hole is there
