Unit Check (Quick Check): GPS

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

Pressing the Information button displays more GPS signal detail.
