Circuit/System Testing

WARNING: This page is about a different car, the 2008 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: The global positioning system (GPS) requires a clear line of sight to the sky to operate properly. In most cases the GPS will not have reception near tall buildings or inside structures.
  1. Disconnect the GPS antenna coax cable from the navigation radio.
  2. Ignition ON, test for 4.5-5.5 volts between the radio coax cable connection center conductor and ground.
    • If the reading is not within the specified range, replace the radio.
  3. If all circuits test normal, replace the GPS antenna.
