DESCRIPTION AND OPERATION

GPS Antenna

The GPS antenna is located underneath the air intake
plenum. The antenna is connected to the GPS
receiver via a single co-axial cable and passes signals
received from the GPS satellites to the 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-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 CD map until the signal is restored.
