Navigation System Components and Features (if equipped)

WARNING: This page is about a different car, the 2013 Buick Regal. However, it is still accessible from the selected car via links, so may be relevant.

The navigation system, if equipped, provides the following:

Connection to the global positioning system (GPS) antenna, which provides the vehicle position information.
Map data for navigation and map route guidance. dependent on vehicle equipment, this data may be stored internally, or externally on an SD card connected to the radio via USB.
Route guidance with verbal prompts to the operator.
Traffic and weather information for display on the navigation system map (with active subscription, where available).

Global Positioning System (GPS) Antenna

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

The antenna is connected to the navigation radio through a signal splitter. The signal splitter is a component for dividing the navigation signal into two paths without any transmission loss. This allows the use of a single GPS antenna to provide a signal to both the navigation radio and the telematics communication interface module.

SD Card Reader (if equipped)

When not equipped with internal storage, the navigation system has a USB port with SD card reader slot located in the center 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.

The system uses the 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.

Route Guidance

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 signal. and serial data information to accurately display the current position of the vehicle.

Points of Interest

The map database provides point of interest information. Points of interests are locations that are frequently visited. Points of interest can be can be displayed on the map or set as a destination. The following are some of the available Points of interests:
