• The electronic anti-theft protection is equipped with a protection code number.
• For proper function of the RNS, rotation angle sensor in unit must be set corresponding to installation position of unit in the vehicle. Therefore, always pay close attention to the replacement part number when replacing the unit. The RNS (Radio Navigation System) will not work properly if the incorrect radio is installed.
• After connecting the battery, check all the vehicle accessories, (radio, the clock, the Convenience Systems). Refer to and the Owner's Manual.
• If a magnetic antenna is mounted on the roof, the compass module could malfunction due to interference from the magnet or because the roof becomes magnetized. There may be issues with an incorrect compass display if a magnetic antenna was used.

Troubleshooting
The RNS is equipped with On Board Diagnostic (OBD).
Use the Vehicle diagnostic tester under "Guided Fault Finding".
Electronic Anti-Theft System
The Radio Navigation System (RNS) is equipped with an electronic anti-theft system which operates in conjunction with the instrument cluster. The radio code is stored internally inside the RNS and inside the instrument cluster.
After disconnecting the power supply to the RNS, it is ready for use and the radio code does not need to be entered again. The requirement is that the first activation of the electronic anti-theft system follows and that the RNS is reconnected in the same vehicle.
Use the Vehicle diagnostic tester to get the radio code. The radio card and the label on the RNS that were used in the past are no longer used.
• The Vehicle diagnostic tester must be online (connected to the network) in order to get the radio code and the user must be authorized to access radio codes.
Electronic Anti-Theft System, Deactivating
Reactivating a locked RNS is only possible by entering correct radio code number for anti-theft protection.
Determine the anti-theft code using the Vehicle diagnostic tester
- Connect Vehicle diagnostic tester.
- Select Guided Fault Finding.
- Using the Go To button, select "Functions/Component selection" and the following menu options in sequence:
• Body
• Electrical Equipment
• 01 - On Board Diagnostic (OBD) capable systems
• Radio/navigation system
• Radio/navigation system functions
• Radio code inquiry
An authorization to the system will be requested: Then the operating data, the VIN and the radio serial number of the radio/navigation system will be automatically read out.
• The Vehicle diagnostic tester may not be able to read the radio/navigation serial number when a new radio/navigation unit is installed. In this case, enter the serial number manually. The serial number can be found on a sticker on the radio and is also stamped into the side of the unit.
The Vehicle diagnostic tester will display the anti-theft code.
The radio navigation system anti-theft code must not be entered manually.
Electronic Anti-Theft System, Deactivating:
- Switch on radio navigation system.
"SAFE" appears in the display for approximately 10 seconds, after that "1000" appears.
- Enter the correct radio code using the buttons on the radio.
- Press the input screen to confirm in the entry.
The RNS is enabled and ready for operation.
Use the correction screen to erase an incorrect code.
It is possible to enter the radio code again if it was entered incorrectly. If radio code is entered incorrectly twice, then the RNS is locked for an hour. Leave the RNS and ignition on. The process can be repeated again after an hour. Note: Always two attempts, after that the RNS will lock up for one hour.
