Troubleshooting
The path guide can be different from the actual path.
(Path guide error)
• When the road is closely parallel.
• When the splitting road angle is very small.
• When there is an adjacent road when turning.
• When driving on a road that is narrowing fast.
• When driving through the mountain or where the road is too curvy.
• When the starting, passing and arriving locations are too close within 1km.
• When you have set the starting, passing or arriving location more than 1km away from
the road.
• When driving through the tunnel.
• When driving through high buildings.
Map matching
As mentioned, the GPS systems used by this Mobile Navigation System are susceptible to
certain errors. Their calculations may on occasion place you in a location the map where
no road exists. In this situation, the processing system understands that vehicles travel
only on roads, and is able to correct your position by adjusting it to a nearby road. This is
called map matching.
With map matching. With no map matching.
