Automatic Distance Correction Check
The mobile navigation system calculates and indicates the vehicle position on the
map by multiplying the speed pulse emitted by the vehicle with a correction coeffi-
cient. The speed pulse emitted varies with the type of vehicle, and differences in tyre
pressure and wear. A different correction coefficient might be required even for the
same type vehicles.
The system corrects distance deviations automatically based on GPS data. To be
able to use the system effectively in the following cases, make sure to carry out the
procedure described below.
•  Before initial use
•  After a tyre change
•  After tyre rotation
•  When installing a navigation system previously installed
in another vehicle
Press SET UP to open the [Setup Menu].

Press POS to return to the map display.
Drive your vehicle for about 30 minutes with the Current Position Map displayed.
a As the distance correction coefficient becomes more accurate, any deviation
between the actual vehicle position and that on the map is eliminated.

Important Notes:
• Do not start driving until the opening screen closes.
• You should drive at an average speed of at least 20 km per hour in the
open area for reception of GPS signals.
• The mobile navigation system uses GPS data for distance correction.
Make sure that GPS signals are being received (checking for GPS recep-
tion is described on the next page).
Depending on the Vehicle Model
The vehicle position indicator may disappear temporarily after speed raised. This is a
normal phenomenon indicating that the system is calculating for distance correction.
