Additional information
How you are guided
• If GPS signal reception is poor, navigation guidance
may not be correct.
• The System may not receive GPS signals in the
following places...
– in a tunnel or parking lot in a building
– under an overhead road
– in a place surrounded by high buildings or by
closely standing trees
• Make sure to connect reverse signal lead
(☞ Installation/Connection Manual); otherwise, your
current position may not be displayed correctly.
• The position of your car may not be detected correctly
in the following cases...
– when driving on a road close to the other one
(e.g. a highway and ordinary road running in
parallel)
– when turning at an almost straight fork in the
road
– when driving on a gridiron road
– after taking a ferry, etc.
– when driving on a steep mountain road
– when driving on a spiral road
– when turning left or right after running on a long
straight road
– when driving in a zigzag line on a broad road
– when starting your car shortly after starting the
engine
– when driving for the first time after installing the
unit
– when changing tires or attaching chains on the
tires
– when tire slip occurs continuously and frequently
– after driving on areas other than a road (e.g.
private lands or parking lots)
– after driving in underground or tower type
parking lots
– after rotating your car on a turntable
– after frequent stops and starts in a congestion
– when the accuracy of GPS is deteriorated
intentionally
– when driving on a road constructed recently
• The route calculated by the System is one of the
possible routes to your destination. The route is not
always the most appropriate one.
• If no-exit roads (only entering the rotary from the
roads is allowed) exist on the rotary, the no-exit
roads can neither be shown in the route guidance on
the display nor counted in the route guidance voice
message.
• The following phenomena may occur even if the
System is working correctly...
– It may guide to a closed road or to a route
requiring a U-turn.
– It may not guide to your destination if there
is only a narrow road or no road to your
destination.
– It may show a different road name.
– It may not ask you to turn at a junction even if
you need to.
– It may give guidance different from the actual
road conditions.
– It may give incorrect distance information.
