Unit Check (Quick Check): GPS

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