• An anti-theft protection message appears on the factory audio display.
• A new or used replacement head unit has been fitted.
• The head unit is being assessed for legitimate replacement or reinstallation.

• The existing listing includes selected NTG 3.5, 4.5/4.7, 5.0/5.2, 5.1, 5.5 and NTG6 MBUX applications.
• Support is confirmed against the actual head unit, serial number and current service availability.
• Do not assume every vehicle with the same model badge uses the same unit or activation procedure.

Send a clear photo of the displayed message and the head unit label or serial number, if available. Explain whether it is the original unit or a replacement. Provide proof of ownership or lawful parts provenance when requested. Keep serial numbers and vehicle documents in your private enquiry.

Is this an ignition or immobiliser service?

This listing concerns audio head unit anti-theft activation. Discuss any other vehicle fault separately.

Can a generated PIN be cancelled?

A code prepared for a specific head unit may not be reusable. Confirm the serial number, service scope and cancellation terms before authorising preparation. Your Australian Consumer Law rights continue to apply.

Send your enquiry before ordering or sending a unit. NAVIPLUS will confirm compatibility, the agreed work, assessment arrangements and pricing. Any parts, additional services, turnaround estimate and applicable warranty terms will be specified in your quotation.

Your rights under Australian Consumer Law continue to apply. A displayed enquiry price is not confirmation that the service is free.
