Troubleshooting
There is a difference between the driving
road and the road on the map in the product.
Even though GPS is usually very accurate, it
has an error range.
When GPS receiver is installed, there can be an
error of about 5 to 15m. But for newly construct-
ed roads, the problem could be from the data
update to the map.
What is GPS?
The Global Positioning System (GPS) is a
satellite-based navigation system made up of
a network of 24 satellites placed into orbit by
the U.S.
Department of Defence. GPS was originally
intended for military applications, but in the
1980s, the government made the system
available for civilian use.
GPS works in any weather conditions, any-
where in the world, 24 hours a day.
There are no subscription fees or setup
charges to use GPS.

Map matching
The GPS used by this Mobile Navigation
System is susceptible to certain errors. Their
calculations may on occasion place you in a
location on 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 near road. This is
called map matching.
With map matching.
With no map matching.
