Audi A3 Sat Nav - Aux not working


Novice Member
I recently upgraded the radio in my A3 to the "Audi Navigation Plus"
Since I installed this the AUX port in my car hasn't worked. Although there is still an option for this on the radio under Media > Source it doesn't work when you attach a device to the AUX.

Also as the phone connects to the system via bluetooth for phone calls, is there any way you can play music from the phone through the unit?

I have searched quite a few forums on the internet for this but have been unable to find a solution.

If anyone has any possible solutions that would be great.

To get the AUX port to work you need to obtain a plug for the socket above the yellow sticker on the back of your radio and move the three wires for the AUX port from the main connector block to this new plug.
Alternatively if you don't want to play with the wiring loom you could get an RNS-E AUX adapter from ebay which consists of the plug and a lead with a jack plug on the end. You could route the lead to the glove box or other convenient location.

The standard bluetooth doesn't support music playback. Bluetooth adapters that plug in to the cd changer port on the radio are available but I don't know how well they work. I decided to just fill a couple of SD cards with MP3 files.
