Technical data

Infotainment system 225
When any of those situations occurs,
the GPS satellite will automatically
adjust the current position fix if you
keep driving.
Problems caused by map files:
• When you return from a road
which is newly constructed to a
road recorded in map file, you
may find floating point swings
because the map file may not
reflect the real road conditions.
After you keep driving for a while,
the system will adjust it to the
right position using GPS signal
information
• No through way due to road
closure or pedestrian path
• Open of a new road and closure
of old road;
• Guide to a no-through way;
• Route re-computed again without
changing the proposed route;
• Guide to a normal road instead of
a viaduct, or vice versa;
• If there are only small lanes
without a normal road near the
destination, the system will only
guide you to a place near to your
destination;
• Instruct you to make a U-turn;
• No indication at a branching road;
• Turning instruction mismatch the
real road condition;
• No indication of direction or voice
prompt about entrance/exit while
guiding on highway/expressway.
• Schematic map may mismatch
real road conditions.
Places having difficulties to
receive GPS signals
• In tunnels;
• Between high buildings;
• Under viaducts;
• In trees/forests;
When using external GPS antenna,
we recommend that you place it on
the roof of the car. If there is rack on
the roof of your car, please make
sure to separate the rack and the
antenna.
GPS is managed by the department
of defense of USA. It may purposely
reduce the accuracy of the GPS
signals so that the car may swing.
Use Notice
• The floating point may swing
before the GPS signal is received
when you turn the power on.
• The floating point may swing
when you use the system at the
first time after installation.
• The system will automatically
adjust its position and direction
using GPS signals when the
floating point mismatches real
condition.
