Anyone know how to get into the computer of a navigation? I have a "Joystick" type navigation i believe it came out of a 05 Rendevous. I've been searching on how to get into the computer on it but no luck. They said press the "Nav Rpt" button then the "Music Note" Button but it dont do anything. Anyone have any knowledge? The Part # is 10351123 if that helps ya? Thanks!!!!!!!!!!!!!!!
