1. Understanding the Audi RNS-E System

The Audi RNS-E is a navigation and entertainment system found in various Audi models. While it offers a range of features, adding an auxiliary (AUX) input can significantly expand its audio capabilities. This allows you to connect external devices like smartphones, MP3 players, or other audio sources directly to your car’s sound system.

1.1 RNS-E System Overview

The Audi RNS-E (Radio Navigation System Europe) is a factory-installed infotainment system that was popular in Audi vehicles manufactured from the early to late 2000s. It typically features a 6.5-inch color display, GPS navigation, CD/DVD player, and radio functionality. While the RNS-E offers several features, it lacks a standard AUX input in many models.

1.2 The Need for AUX Input

In today’s digital age, many drivers rely on their smartphones or portable music players for audio entertainment. Adding an AUX input to the RNS-E system provides a convenient way to connect these devices and enjoy personalized music, podcasts, or audiobooks through the car’s speakers.

2. Essential Parts and Tools

Before embarking on the Audi RNS-E AUX installation and VCDS coding process, you’ll need to gather the necessary components and tools. Here’s a comprehensive list:

Locate the grey 32-pin AV connector on the back of the RNS-E unit.
Insert the female repair wires into the following pins on the connector:
- Aux In Left – pin 22
- Aux In Right – pin 6
- Aux In Ground – pin 21
Connect the other ends of the repair wires to the corresponding wires on the 4-pin harness for the Aux-in plug.
Ensure all connections are secure and properly insulated.

3.4 Installing the AUX Plug

Choose a suitable location for the AUX plug in your car’s interior.
Drill a hole (if necessary) to accommodate the plug.
Secure the AUX plug in place.
Route the 4-pin harness from the RNS-E unit to the AUX plug location.

4. VCDS Coding for AUX Activation

After the physical installation of the AUX input, you’ll need to use VCDS (Vag-Com Diagnostic System) to enable the AUX functionality in the RNS-E system.

4.1 Connecting VCDS

Connect the VCDS cable to your car’s OBD-II port.
Turn on the ignition.
Launch the VCDS software on your computer.

4.2 Accessing the RNS-E Module

Select “Select Control Module” in VCDS.
Choose “37 – Navigation.”

4.3 Adaptation

Select “Adaptation – 10”
Enter channel number “002”
Read the current value. It will likely be a number like 00000.
Add the appropriate value to enable AUX:
- Add 2 to enable AUX only
- Add 3 to enable AUX and SAT radio
Test the new value.
Save the new value.

Example: If the current value is 00000, and you want to enable AUX only, the new value would be 00002.

4.4 Verifying the Coding

Exit the Adaptation function.
Go back to the main screen and select “Fault Codes – 02”.
Check for any new fault codes related to the RNS-E system. If there are any, clear them and recheck.
