MARK I NAVIGATION SYSTEM CALIBRATION
The Mark I navigation system will require calibration at some point in its service life. The
reasons that cause the necessity of a calibration procedure are as varied as inaccurate
navigation display data, after the installation of a new set of tires, to the replacement of a
shattered rear window.
Calibration procedures are divided into two categories
Vehicle Owner Calibration -
Calibration that the vehicle owner can perform.
Dealership Calibration -
Procedures only an authorized dealer can perform.
This section is divided into these two categories. Always consider what the owner of the
vehicle could have inadvertently changed when troubleshooting and/or calibrating the vehicle.
Check these data inputs
before
you embark on a full dealership calibration procedure.
VEHICLE OWNER CALIBRATION
The vehicle owners manual contains the information on how to set the vehicle position and
adjust the tire calibration. Both of these adjustments are found on the vehicle position
screen which is accessed from the information screen as shown on page 24.
The Owner Calibration Procedures shown on pages 25-27 are for information
purposes only. A full Dealership Calibration is the recommended method for
accurate system calibration.
1. RESETTING VEHICLE POSITION
A mis-located vehicle is caused by driving in and out of the digitized map areas or starting
a vehicle after it has traveled on a flat bed or train. The system will eventually relocate itself
automatically through GPS but it can be entered through the on-board monitor for
immediate resetting.
From the Vehicle Position Screen, rotate
the knob to city: and push the knob.
Enter the city and street information as you
would enter a destination. Press the
Intersection button and select the
closest intersecting street from the
displayed index.
Drive to the entered intersection and press
the Crossing the intersect. button when you cross.
Drive the vehicle to see if it is
positioned correctly.
