powered through the same coaxial cable used to send the signals to the navigation radio. The GPS antenna
collects data from the GPS satellites and routes this information to the navigation radio to be formatted into
current position.

GPS Reception

The global positioning system (GPS) shows the current position of the vehicle. Tall buildings, large trucks, or a
tunnel can obstruct GPS signals. Metallic objects on the dash can also cause interference. A GPS icon is located
in the top left corner of the map display. If the GPS is valid, the icon will be green if not the icon will be gray.
The GPS info screen will also show the condition of the GPS. If GPS reception in not received, it will show out
of range. If the reception is received, the coordinates of your location will be shown.

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 as well as
the vehicle speed signal to accurately display the current position of the vehicle.

Point of Interest (POI)

Points of interests (POI) are locations that are frequently visited. Points of interest can be displayed on the map
or set as a destination. The following is a few of the available POI:
