Unit Check (Quick Check): GPS
If GPS indicates NG (Antenna), then check the entire GPS antenna wire from the audio-navigation unit to the GPS antenna. If the wire is crushed or damaged, substitute a known-good GPS antenna (see GPS ANTENNA REMOVAL/INSTALLATION ). If the diagnostic reads OK, replace the original GPS antenna (see GPS ANTENNA REMOVAL/INSTALLATION ). If the diagnostic still reads NG (Antenna), replace the audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ).
