Navigation System Description and Operation

Each item in the list below represents topics covered in detail below.

The Navigation radio operates similar to a traditional radio. For information on the audio description and operation, see Radio/Audio System Description and Operation .

The navigation system contains the following components:

The navigation radio is located in the centre of the instrument panel. The navigation radio provides the following:

The info display module has continuous power and ground. When the navigation radio is on, a discrete 12 V signal is supplied on the remote enable circuit to the colour display module. This signal is used to control the power state of the module, which is active when the signal is high and inactive when the signal is low.

The info display module receives digital video data from the radio for on-screen display information through the video signal circuits. The radio communicates with the info display module over the touch screen serial data circuits for touch screen inputs and back lighting dimming level.

When equipped with the navigation radio, the radio controls communicate radio control inputs directly to the navigation radio with the CAN Graphical Interface (CGI) data circuits. After receiving the message the radio will perform the requested function. Messages communicated between the radio and the radio controls include the following:

The HVAC controls are a separate component from the radio controls. HVAC data for controls and status indicators is communicated between the HVAC controls and the HVAC control module with a separate LIN serial data circuit. HVAC status screen information from the HVAC control module is transmitted to the radio on the GMLAN serial data circuit. The radio then displays the desired screen information on the info display using the video data circuits.

The global positioning system (GPS) aerial is part of the multi-band aerial located on the roof of the vehicle. The GPS aerial is used to collect the signals of the orbiting GPS satellites. Within the aerial is housed a low noise amplifier that allows for a more broad and precise reception of this data. The GPS aerial amplifier is powered through the coaxial cable.

The infotainment system has a 3.5 mm (1/8 in.) auxiliary audio input jack located in the centre console. When a portable audio playback device is connected to the auxiliary jack, an internal switch detects the connection and the radio will switch to AUX as the audio source. Audio signals from the device are sent to the radio from the auxiliary jack via the left, right, and common audio signal circuits.

The navigation system has a USB port and SD card reader slot located in the centre console. The USB port and the card reader slot interface with a hub device, internal to the auxiliary jack, USB, and memory card receptacle assembly. The internal hub device interfaces directly with the radio via a USB cable. The auxiliary jack, USB, and memory card receptacle assembly receives fused battery voltage and ground from the harness to power the internal hub device as well as providing additional amperage to power USB devices.

USB Port

When a device is connected to the USB port, the system detects the device and switches to USB as the audio source. Once connected, the device can be controlled from the radio controls. The USB connector supports both USB standards 1.1 and 2.0.

USB Supported Devices:

Depending on the USB device, some devices may not be recognised, or some features/functions may not be able to be controlled with the radio controls. USB HUB devices are not supported. Refer to the Owners Manual for additional information.

SD Card Reader

The navigation system in this vehicle uses an SD Card to store map information. The map database SD card must be inserted in the console SD card reader slot for the navigation system to function. If the map database SD card cannot be accessed, navigation related selections will not be available to the infotainment system. The SD card reader is dedicated for map data only, no other file types are supported.

The map will display the route to the selected destination. Voice prompts alert the operator of upcoming events (turns) and arrivals at the destination. The navigation system will automatically recalculate if the route is not followed. The navigation radio uses data received from the global positioning system (GPS) satellites, the vehicle speed and other serial data information to accurately display the current position of the vehicle.

The Navigation System's voice recognition allows for hands-free operation of navigation and audio system features. The voice recognition can be used when the ignition is in accessory or ON, or when retained accessory power is active. For a complete list of available commands, refer to the Owners Manual Navigation Supplement and/or Personalisation in the Owners manual.
