LR3/Disco 3
The GPS antenna is located in a pod which is in the in the center on the vehicle roof at the rear. The GPS antenna is
connected to the GPS computer by a single co-axial cable and passes signals from the GPS satellites to the navigation
computers built in receiver for processing.
It is possible for the GPS antenna to lose the GPS signal from the GPS satellites in hilly or tree lined areas, built up areas
with tall buildings, multi storey 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 DVD map until
the signal is restored.
Traffic Message Channel (TMC) Receiver
The Traffic Message Channel (TMC) receiver is located in the rear RH side of the luggage compartment. The TMC
receiver is connected to the MOST ring and transmits TMC data to the navigation computer (via the TSD). The navigation
computer then displays this information on the TSD and also re-routes the navigation guidance around any traffic hold
ups. The TMC data is received via the FM antenna located in the rear screen via an antenna amplifier located above the
rear tailgate spoiler. For additional information, refer to
Antenna
