Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.
