I have the D-3 and had the installer install the module that keeps the Onstar and steering wheel buttons working. When I went into try to do the bypass I noticed that the RCA harness isn’t even used. So I skipped the part about moving the mute white since I assumed it wasn’t even an option. So I went ahead and grounded the parking brake, now the menu states that the parking brake is on but after going faster than like 5-10mph the screen goes blank giving me a message about driving while watching is unsafe. What am I missing since there is no option to move the mute wire?
