• Sometimes, when you are driving on the
highway/viaduct, the floating point swings.
• When you are driving on a very steep road.
• When you are driving on spiral road, you
will find that the floating point swings. It
is nothing to do with the radius of the road
and the driving speed of your vehicle. One
reason might be that the real road condi-
tion may differ from the information of the
electronic map.
• When you make a right/left turn to enter
a road and that has parallel roads nearby
(less than 50 m distance), you might find
that the floating point may go to another
road.
• When driving on a wide road in a snaky
line, you may experience that the floating
point may swing due to the mismatch of
real distance.
• Before returning to a ground road after you
have been driving in an underground car
park or a spiral path of the multi-level car
park, you will find that the floating point
may swing. When your car is in a rotary
elevator, the arrow of the floating point
may not point to the right direction.
• Providing voice prompt at a branching path
ahead.
• The guided distance may deviate from the
actual distance rate.
When any of those situations occurs, the GPS
satellite will automatically adjust the current
position fix if you keep driving.

• 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 re-
flect 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 chang-
ing the proposed route;
• Guide to a normal road instead of a via-
duct, or vice versa;
• If there are only small lanes without a
normal road near the destination, the sys-
tem will only guide you to a place near to
your destination;
