A French Macintosh user, Elie, has managed to connect an Apple PowerBook G4 to the navigation/display system in his Audi A6. With the assistance of an Audi technician, Elie wired the computer into the navigation system’s hidden AV inputs. According to the report, it was necessary to dismount all the audio and navigation components in the trunk and to find the connectors.
