The RCD 210 radio, found in various Volkswagen and Audi vehicles, often lacks a readily available AUX input. However, with a VCDS (VAG-COM Diagnostic System) interface and the right coding, you can activate the AUX functionality. This guide will walk you through the process of enabling the AUX input on your RCD 210 using VCDS.
While the RCD 210 appears to lack an AUX port, the necessary hardware is often present. By using VCDS, we can modify the radio’s coding to recognize and activate this hidden feature. This allows you to connect external audio devices, such as smartphones or MP3 players, to your car’s audio system.
To begin, you’ll need a VCDS interface and the corresponding software installed on your laptop. Connect the interface to your vehicle’s OBD-II port and launch the VCDS software. Once connected, navigate to the following modules:
- Select Control Module: Choose “56 – Radio.”
- Security Access: Enter the security access code if prompted. This code is specific to your vehicle and radio model. You may need to consult online resources or your vehicle’s documentation to obtain it.
- Adaptation: Go to the “Adaptation” section.
- Channel: Locate Channel 17. This channel typically controls the AUX input activation.
- Value: Change the value in Channel 17 to “1.” This will enable the AUX input. If the default value is already “1” but the AUX input is still not working, try other values like “2” or “3,” but always note down the original value before making any changes.
- Test: After changing the value, save the changes and test the AUX input. You should now be able to connect an external audio device and hear the audio through your car’s speakers. If the AUX input still doesn’t function, double-check the wiring and connections to ensure everything is properly connected.
Enabling the AUX input on your RCD 210 with VCDS offers a simple and cost-effective way to enjoy your favorite music in your car. This process typically works for various Volkswagen and Audi models equipped with the RCD 210. However, always remember to note down the original coding before making any changes. This allows you to revert to the original settings if necessary. Consult online forums or your vehicle’s documentation for specific instructions related to your car model and radio version.
