RHD ModelsNJEL0523S0301By integrating the Navigation System in the vehicle's interior and linking it to the vehicle's immobilizer system,
the possibility of the Navigation unit being stolen is effectively reduced. Each time the Navigation System is
switched on, the Navigation System will start up communication with the vehicle's immobilizer control unit
(IMMU) and verify an identification code. If communication cannot be established, or the verified code is
incorrect, the Navigation System will lock up showing ªANTI-THEFT FUNCTIONº on the Navigation display.

PIN INITIALIZATION Navigation system will be locked when the vehicle's owner enters the wrong PIN five con-
secutive times.
To release the lock, use ªPIN INITIALIZATIONº.
NAVI ID INITIALIZATION In normal times regulation codes are being communicated between Navigation Control
Unit and Dongle Control Unit.
Use ªNAVI ID INITIALIZATIONº to match the codes when either one has been replaced
due to breakdown or etc.
NOTE:
When any initialization is performed, all NAVI ID and PIN pre-
viously registered will be erased and then must be registered
again.
