WARNING: This page is about a different car, the 2008 Buick Lucerne. 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.
- Ignition OFF, disconnect the GPS antenna coax cable from the navigation radio.
- Ignition ON, test for 4.5-5.5 volts between the radio coax cable connection center conductor and ground.
- If not within the specified range, replace the radio.
- If all circuits test normal, replace the GPS antenna.
