it does not appear to be functioning properly, please follow the troubleshooting
guidelines below.

• Check the satellite icon in the upper right corner
of the map view screen.
• Make sure the antenna on the unit is pointed
outward and upward with a clear view of the sky.
• Ensure that the vehicle does not have a heat-
