2006-2012 Bentley Continental & Flying Spur Navigation DVD Drive Failure: Diagnosis and Replacement

Key Vehicle-Specific Information

This guide covers the DVD-based navigation drive, identified by part numbers like 3W0919887F, found in the 2006-2012 Bentley Continental (GT, GTC) and 2006-2012 Bentley Flying Spur. These vehicles share the same infotainment architecture. It's important to distinguish this DVD-based system from the earlier CD-based systems (found in ~2003-2007 models) and the later Hard-Drive (HDD) based systems (found in ~2012 and newer models). This article specifically addresses the DVD drive located in the glove compartment.

Common Symptoms of a Failing Navigation DVD Drive

When the navigation drive begins to fail, you will notice issues specifically related to map and navigation functions. The radio, climate controls, and other infotainment features may still work correctly. Here are the most common signs of failure:

• "Navigation not available" or "Insert Navigation DVD" Error: The most frequent symptom is an error message on the main screen indicating that the system cannot read the map disc, even when one is inserted.
• System Stuck on Bentley Logo: The entire infotainment screen may get stuck on the Bentley splash screen or continuously reboot. This happens when the main system fails to initialize the faulty navigation module.
• Constant Disc Spinning Noise: You may hear the drive in the glovebox constantly spinning, clicking, or attempting to read the DVD without success.
• Parasitic Battery Drain: A faulty navigation drive can fail to shut down properly when the car is turned off, leading to a dead battery after the vehicle sits for a day or two.
• System Stuck in German: In some failure modes, the infotainment system may revert to German and lose the ability to change languages.
• Diagnostic Fault Codes: A professional scan tool may report a fault code for the navigation control unit, indicating it is faulty or not communicating.

Diagnosing the Problem

Before buying a replacement part, follow these steps to confirm the navigation drive is the culprit:

1. Inspect the DVD: Eject the navigation DVD from the drive in the glovebox. Check it for deep scratches, cracks, or smudges. Clean it with a soft, lint-free cloth and re-insert it. Forum users note these drives can be very sensitive to disc condition.
2. Try a System Reset: For some software-related glitches, a reset can restore functionality. On later models (around 2012), you can perform a three-button reset by pressing and holding the three buttons at the top of the infotainment screen simultaneously until the screen goes blank and reboots. An alternative is a "fuse pull" reset by temporarily removing the fuses for the infotainment system.
3. Test with a Different Disc: If possible, test your system with a known-good, compatible Bentley navigation DVD. If another disc works, your original DVD is the problem. If the other disc also fails to load, the drive itself is almost certainly faulty.

Programming and Anti-Theft Requirements

This is a critical topic for anyone replacing this module. Fortunately, the process is straightforward.

• No Dealer Programming Required: A replacement DVD navigation drive with a matching part number does not need to be programmed or coded by a Bentley dealer. It is a plug-and-play component. Repair shops confirm that claims of needing dealer coding are generally false for a like-for-like swap.
• 4-Digit Security PIN: Some units are linked to the car with a 4-digit security PIN. When installing a used unit, it may ask for this code. If you can get the code from the donor vehicle's paperwork, it simplifies the process. However, even if you don't have the code, many independent radio repair shops can retrieve or reset it. This is an anti-theft measure, not a complex immobilizer function.

Buying a Used GPS Navigation System

Given the extremely high cost of a new OEM unit from Bentley, a used OEM part is the most practical solution for most owners. Here’s what to look for:

• Verify the Part Number: The most important step is to match the part number. Remove your original unit from the glovebox and find the sticker on the casing. Match the part number (e.g., 3W0919887F or 3W0919887GX) with the used part you intend to buy.
• Check Compatibility: Ensure the donor vehicle falls within the correct generation. A drive from a CD-based system (pre-2007) or an HDD-based system (post-2012) will not work in your DVD-based vehicle.
• Physical Inspection: When you receive the used part, inspect the case for any signs of physical damage or water intrusion. Ensure the connectors are clean and free of corrosion.
• Ask for the Security Code: If possible, ask the seller if they can provide the 4-digit security PIN from the donor vehicle. While not always essential, having it can make installation smoother.
• Why Used OEM is a Good Choice: For this part, a used OEM unit is a reliable and cost-effective option. Aftermarket solutions typically involve replacing the entire infotainment system at a very high cost and complexity, often with a less-than-factory finish. A used OEM drive maintains the original functionality and appearance of your vehicle's interior.

Replacement Procedure Overview

Replacing the navigation drive is a simple DIY task that can be completed in under 30 minutes.

1. Location: The unit is located inside the glovebox, typically on the upper shelf.
2. Removal: It is held in place by a few screws. Once the screws are removed, the unit can be slid forward.
3. Disconnection: Carefully disconnect the electrical connectors from the back of the unit.
4. Installation: Connect the new unit, slide it back into place, and secure it with the screws. Power on the car to test functionality. You may be prompted to enter the security code if it's from a different vehicle.
