The Kenwood DNX994S offers seamless integration with a vehicle’s systems, including the backup camera. However, some Toyota FJ Cruiser owners have reported issues with the backup camera guide lines and other functionalities after installing the DNX994S. This article outlines troubleshooting steps and potential solutions based on real-world experiences.
Common Issues and Troubleshooting Steps
One common issue is misaligned backup camera guide lines. When the vehicle is put in reverse, the lines may point slightly to the left even with the steering wheel straight. A Kenwood engineer suggested flashing the DNX994S with diagnostic firmware to analyze steering angle readings and diagnose the problem. This process involves removing the unit, flashing the firmware, and then running diagnostic screens with Kenwood support. While inconvenient, direct access to the module is often necessary for this procedure.
Another reported issue involves the illumination/dimmer function. The DNX994S offers “Sync,” “On,” and “Off” options for this feature. However, distinguishing between these settings can be difficult during daylight hours. Testing in a low-light environment is recommended to verify proper dimmer functionality.
Finally, some users have reported discrepancies in the door ajar alert system. The DNX994S should display an alert when a door is open and the vehicle is moving above a certain speed (5-10 mph). Additionally, the vehicle info screen should indicate which door is open. However, this functionality may not always work as expected in the FJ Cruiser. While not a critical issue, as the dome light and gauge indicators provide sufficient warning, it highlights potential integration challenges.
Solutions and Considerations
The diagnostic firmware update provided by Kenwood addresses the misaligned guide lines issue. Working directly with Kenwood support is crucial for this process. For the illumination/dimmer function, experimenting with the different settings in low-light conditions can help determine the optimal configuration. Regarding the door alert system, relying on the vehicle’s existing warning systems might be the most practical solution for now.
Conclusion
Integrating aftermarket head units like the DNX994S into vehicles like the Toyota FJ Cruiser can present unique challenges. While issues with backup camera guide lines, dimmer functionality, and door alerts can arise, working directly with the manufacturer’s support and utilizing available resources, such as diagnostic firmware updates, can lead to effective solutions. This collaborative approach, combined with user feedback and shared experiences, is invaluable in resolving these integration complexities.
