Hi Korvan just need some info.I done the mod but with only the park brake wire, when i disengage the park brake it works but when the car starts moving the screen goes blank do i need to do the complete mod or do i have a bad earth.Im pretty shore its not the earth as it works until the car starts moving or until i engage the park brake.Ive got an 06 prestige.Please help.
