Unit Check (Quick Check): GPS

If GPS indicates NG (ANT), then check the entire GPS antenna wire from the audio-navigation unit to the GPS antenna. If the wire is crushed or damaged, try a known-good antenna. If the diagnostic reads OK, replace the original GPS antenna. If the diagnostic still reads NG (ANT), replace the audio-navigation unit.
