The RCD 210 radio unit, found in various Volkswagen and Audi vehicles, often includes an auxiliary (AUX) input for connecting external audio devices. However, this feature may be disabled by default. This guide explains how to activate the AUX function on an RCD 210 using VCDS (Vag-Com Diagnostic System).
VCDS, a diagnostic software for VAG (Volkswagen Audi Group) vehicles, allows access to various control modules, including the RCD 210. By adjusting specific coding within the radio’s settings, the hidden AUX input can be enabled. This process typically involves accessing the “Adaptation” channels within the RCD 210 module using VCDS.
While the specific steps might slightly vary depending on the vehicle model and RCD 210 variant, the general procedure remains consistent. After connecting VCDS to the vehicle’s OBD-II port and establishing communication with the RCD 210, users navigate to the “Adaptation” section. Within this section, searching for channels related to “AUX” or “Auxiliary Input” is crucial. The desired channel often allows toggling the AUX function between “activated” and “deactivated.”
Once the correct adaptation channel is identified, changing its value to “activated” and saving the new coding will enable the AUX input. After this procedure, the RCD 210 should recognize the connected AUX device, allowing playback of audio through the vehicle’s speakers. It is important to note that a physical AUX input jack must be present in the vehicle for this method to work. Some vehicles might require additional hardware or wiring modifications if the AUX jack is not factory-installed.
Successfully enabling the AUX input using VCDS provides a convenient way to enjoy music from external devices such as smartphones, MP3 players, or portable CD players through the car’s audio system. This simple modification enhances the RCD 210’s functionality and expands entertainment options for drivers and passengers. It is recommended to consult the vehicle’s specific documentation or online forums dedicated to VCDS coding for precise instructions and adaptation channel numbers relevant to the particular car model and RCD 210 unit. Remember to always exercise caution when modifying vehicle settings with VCDS and ensure a stable connection to avoid potential errors.
