Unit Check (Quick Check): GPS

If GPS indicates NG (ANT), then check the entire GPS antenna wire from the 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 navigation unit. Select information to see the GPS satellite details.
