The RCD 210 radio, a common fixture in many Volkswagen vehicles, often lacks the readily available AUX input. However, if you’re looking to connect your smartphone or MP3 player, enabling the AUX function on your RCD 210 using VCDS is a straightforward process. This guide will walk you through the necessary steps to unlock the hidden AUX functionality using VCDS, opening up a world of audio possibilities within your vehicle.

Understanding the RCD 210 and VCDS

The RCD 210 is a basic but reliable head unit found in various Volkswagen models. While some units come with a factory-activated AUX input, many do not. VCDS (Vag-Com Diagnostic System) is a diagnostic software that allows you to access and modify the control modules within your Volkswagen, including the RCD 210. Using VCDS, you can activate hidden features, troubleshoot issues, and customize your car’s settings. This is particularly useful for enabling the AUX input on RCD 210 units that don’t have it readily available.

How to Enable RCD 210 AUX with VCDS

1. Connect VCDS: Connect the VCDS cable to your car’s OBD-II port and your computer.
