GPS Antenna
The GPS antenna is installed on the rear of the roof, on the vehicle centreline. A diplexer unit on the underside of the
GPS antenna amplifies the radio signals received from the GPS satellites and transmits them through a co-axial cable
to the navigation computer for processing.
Display Unit
The display unit is integrated into the front stowage pocket, above the rear view mirror. The display unit is a colour
Liquid Crystal Display (LCD) that shows the programming menus, route guidance and traffic information. The display
illumination level automatically dims for night time viewing when the exterior lights are switched on.
