• This function compares the route shape the vehicle is travelling to map data using the GPS satellite signals,
and corrects the vehicle's position to the most appropriate road on the map data.

MAP MATCHING OPERATION
Map Matching Remarks
• When using the navigation system for the first time after purchase or for the first time after a long period during
which it was not used, it may take about five to fifteen minutes until the current position is measured.
Also, even during normal use, it may take about two to three minutes for measurement.
• The map matching function proposes route correction on an order of priority other than the currently indicated
route. Therefore, when the navigation unit detects travelling speed or progressive direction errors, it could
mistake the order of priority and fail to correct the route.
• Due to the system operation principles, the map matching function may be unable to determine which route a
vehicle is taking when there are similar roads around the vehicle, and may not correct the vehicle's position
until it can find a particular route.
• While driving on a road that does not exist in the map data or when the actual vehicle's position is far away from
the position indicated by the vehicle locator mark, map matching will not be performed.
• When the route can not be calculated, manually shift the vehicle locator mark to a major road near the
destination and recalculate. Also, in certain map data situations, the distance to the destination calculation may
be different.
• Under the following driving conditions and GPS satellite conditions, the vehicle locator mark may deviate from
the actual position of the vehicle. This does not indicate any breakdown in the system and if driving continues
for a while, the current position will be corrected automatically.
