Avoiding Untrusted Media Devices

When using media devices such as USB and mobile devices, consider the source. Untrusted media devices could contain files that affect system operation or performance and should be avoided.

USB Port

Maps
The Navigation application requires a map database to run. It is stored on an SD card that is connected to the infotainment system. If the map database is not available, a missing SD card error message will be displayed.

SD Card Error Messages
The SD card only works for one unique vehicle. The SD card must pass authentication verification to be used for that specific vehicle. If the SD card has a switch that can be set to read-only mode, ensure that it is in the upward position and not in read-only.

Potential error scenarios and messages include:

• The SD card has been initialized for the first time: “Once initialized, this SD card can only be used for navigation in this vehicle.”
• The SD card is not working properly: “SD card is not functioning properly. (Error Code).” See your dealer if this message appears.
• The SD card is not paired with the existing system: “This SD card is not valid in this vehicle for navigation. See the Owner’s Manual for more detail or visit your dealer. (Error Code).”
• The SD card has been removed from the slot: “SD card has been removed. (Error Code).”
• Make sure the SD card is in the slot. If it was removed and inserted and you still receive an error code, see your dealer.

Touch Confirm to resume after the initialization error message. For the other messages, touch OK to return to the Home Page.

Connected Navigation
Connected Navigation is a subscription service that enables certain capabilities within the navigation system, such as Traffic, Smart Search/Routing, and Predictive Navigation capabilities. The system will show an alert when the subscription is expiring and will ask to renew the plan.

Global Positioning System (GPS)
If equipped, the position of the vehicle is determined by using satellite signals, various vehicle signals, and map data. At times, other interference such as the satellite condition, road configuration, condition of the vehicle, and/or other circumstances can affect the navigation system’s ability to determine the accurate position of the vehicle. The GPS shows the current position of the vehicle using signals sent by GPS satellites. When the vehicle is not receiving signals from the satellites, a symbol appears in the status bar.

This system might not be available or interference can occur if any of the following are true:

• Signals are obstructed by tall buildings, trees, large trucks, or a tunnel.
• Satellites are being repaired or improved.

Vehicle Positioning
At times, the position of the vehicle on the map could be inaccurate due to one or more of the following reasons:

• The road system has changed.
• The vehicle is driving on slippery road surfaces such as sand, gravel, or snow.
• The vehicle is traveling on winding roads or long, straight roads.
• The vehicle is approaching a tall building or a large vehicle.
• The surface streets run parallel to a freeway.
• The vehicle has been transferred by a vehicle carrier or a ferry.
• The current position calibration is set incorrectly.
• The vehicle is traveling at high speed.
• The vehicle changes directions more than once, or the vehicle is turning on a turn table in a parking lot.
• The vehicle is entering and/or exiting a parking lot, garage, or a lot with a roof.
• The GPS signal is not received.
• A roof carrier is installed on the vehicle.
• Tire chains are installed on the vehicle.
• The tires are replaced or worn.
• The tire pressure for the tires is incorrect.
• This is the first navigation use after the map data is updated.
• The 12-volt battery has been disconnected for several days.
• The vehicle is driving in heavy traffic where driving is at low speeds, and the vehicle is stopped and started repeatedly.

Problems with Route Guidance

Inappropriate route guidance can occur under one or more of the following conditions:

• The turn was not made on the road indicated.
• Route guidance might not be available when using automatic rerouting for the next right or left turn.
• The route might not be changed when using automatic rerouting.
• There is no route guidance when turning at an intersection.
• Plural names of places might be announced occasionally.
• It could take a long time to operate automatic rerouting during high-speed driving.
• Automatic rerouting might display a route returning to the set waypoint if heading for a destination without passing through a set waypoint.
• The route prohibits the entry of a vehicle due to regulation by time or season or any other regulation that may be given.
• Some routes might not be searched.
• The route to the destination might not be shown if there are new roads if roads have recently changed, or if certain roads are not listed in the map data. 

To recalibrate the vehicle’s position on the map, park with the vehicle running for two to five minutes, until the vehicle position updates. Make sure the vehicle is parked in a location that is safe and has a clear view of the sky and is away from large obstructions.

If the System Needs Service
If the navigation system needs service, see your dealer.

Map Data Updates
The map data in the vehicle is the most up-to-date information available when the vehicle was produced. The map data is updated periodically, provided that the map information has changed and the vehicle has a relevant service plan. See www.gmnavdisc.com for details on ordering, purchasing, and installing a new or replacement SD card. Features are subject to change. For more information on this feature, visit your brand website.  If the vehicle is equipped with Connected Navigation, which is a subscription service that enables certain features of the navigation system, such as Traffic, Smart Search/Routing, and Predictive Navigation, then the system will download the latest map data from the cloud.

Database Coverage Explanations
Coverage areas vary with respect to the level of map detail available for any given area. Some areas feature greater levels of detail than others. If this happens, it does not mean there is a problem with the system. As the map data is updated, more detail can become available for areas that previously had limited detail.
