Location Correction By Map-Matching Is Slow

WARNING: This page is about a different car, the 2005 Nissan 350Z. 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 of the way map-matching operates, when there are many roads running in similar directions in the surrounding area a matching determination may be impossible. The location will remain uncorrected until some special feature is found.
