The database reflects reality as existing before you received the
database and it comprises data and information from government
and other sources, which may contain errors and omissions.
Accordingly, the database may contain inaccurate or incomplete
information due to the passage of time, changing circumstances, and
due to the nature of the sources used. The database does not include
or reflect information on neighborhood safety, law enforcement,
emergency assistance, construction work, road or land closures, vehicle
or speed restrictions, road slope or grade, bridge height, weight or
other limits, road or traffic conditions, special events, traffic
congestion, or travel time.
Principles of GPS (global positioning system) operation
Your system directs you based on information derived from global
positioning satellites, road maps stored on the DVD, sensors in your
vehicle and the desired destination. The system compiles all necessary
information to guide you to your selected destination. Space satellites
determine the vehicle’s current location and transmit position and time
signals to your car.
If the vehicle has been parked for a long period of time, the navigation
function may be temporarily unresponsive. The navigation system will
operate reliably again once GPS reception is available for a few minutes.
Limited GPS reception
System performance may be adversely affected if GPS reception is
interrupted or interference occurs over a distance of several miles. The
following are possible causes for GPS reception being interrupted. If the
vehicle is:
• in multi-story parking garages
• in tunnels and under bridges
• inside or in between buildings
• by forests or tree-lined avenues
• in heavy rain showers and thunderstorms
• in valleys and in mountainous regions
• roads under cliffs
Ensure that you do not have any metal objects on the rear parcel shelf
and that if your windows are tinted, they use non-metal tinting instead of
metal oxide tinting. Both of these factors can also interrupt GPS
reception.
