Location Correction By Map-Matching Is Slow

WARNING: This page is about a different car, the 2003 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.

The map matching function needs to refer to the data of the surrounding area. It is necessary to drive some distance for the function to work.
Because map matching operates on this principle, when there are many roads running in similar directions in the surrounding area, no matching determination may be made. The location may not be corrected until some special feature is found.
