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 dashboard and
that in your windows are tinted, they use non-metal tinting instead of
metal oxide tinting. Both of these factors can also interrupt GPS
reception.
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.
SYSTEM LIMITATIONS
Cold temperature start: When operating the system below 32° F
(0°C), the display screen requires a 2–3 minutes warm-up time to
achieve maximum brightness.
Other conditions:When calculating a route, the system doesn’t take
into consideration any of the following conditions:
• Traffic Conditions
• Weather Conditions
• Driving Habits
• Construction Zones
• New Roads
