The navigation computer is provided with the front wheel speed signals to track the vehicle
speed/distance and turning.
REVERSE GEAR SELECTED
The nav. computer receives a 12 volt signal from the LCM when the back up lights are
illuminated. This signal informs the nav. computer that the vehicle is being driven in reverse.

When the rear window
defroster is switched on the
nav. computer is informed
via the vehicle bus system:

Video module to the nav.
computer (ARCNET)
When the nav. computer receives
the signal, it compensates for the
magnetic influence from the rear
defroster.
This compensation is derived
from the dealership calibration
procedure.
