DESCRIPTION AND OPERATION
Switch Pack
1 Rotary controller
2 Menu switch
3 Repeat switch
4 Re-route switch
5 Mute switch
The switch pack is installed near the centre of the fascia, below the fascia panel switches. The switch pack contains
the switches for controlling the operation of the navigation system. The switches have the following functions:
Rotary Controller
The rotary controller is a combined rotary and push switch which is used to make all selections when operating the
navigation system. Rotating the switch scrolls up and down a vertical menu, or across a horizontal menu. Pressing
and releasing the switch selects a highlighted item.
Menu Switch
The menu switch is used to activate the system and, when the system is active, return the display to the main menu.
The menu switch is also used to activate and de-activate Trafficmaster.
Mute Switch
Pressing and releasing the mute switches toggles the audio instructions on and off. An orange LED in the switch
illuminates when the mute function is engaged.
Re-route Switch
During road navigation, pressing and releasing the re-route switch produces a menu on the display unit that allows
the driver to select a diversion from the current route of between 0 and 6 miles. Once the deviation distance is
selected, the navigation ECU plots the new route and issues the necessary instructions for the diversion.
Repeat Switch
Pressing and releasing the repeat key causes the navigation ECU to repeat the last audio instruction. The instruction
is only repeated if it is still valid.
Navigation Speaker
The navigation speaker is installed on the back of the lower closing panel on the driver's side of the fascia. The
speaker outputs the audio instructions for route guidance.
