GPS Antenna
WARNING: This page is about a different car, the 2005 Land Rover Range Rover, 2004 Land Rover Range Rover, 2003 Land Rover Range Rover, and 2002 Land Rover Range Rover. However, it is still accessible from the selected car via links, so may be relevant.
The GPS antenna is located in the rear spoiler on the upper taildoor of the vehicle. The antenna is connected to the navigation computer via a single co-axial cable and passes signals received from the GPS satellites to the built in receiver for processing.
It is possible for the antenna to lose the signals from the satellites in hilly or tree lined areas, built up areas with tall buildings, multi story car parks, garages, tunnels, bridges and during heavy rain/thunderstorms. When the signal is lost, the navigation computer will continue to give guidance using memory mapped data from the CD map until the signal is restored.
