Sorry, I should have been more specific. You can plug a connection for the aux into the back of the radio and then fit the aux socket can be installed on the dash. A good place to fit.the aux socket is in one of the switch blanking plates near to the esp light.
So the first pic shows the blanking plates below the left air vent. As you can also see, once the radio is out of the dash you can plug the aux connection in the back.
The second pic shows the type of aux you can fit.
I've also found this YouTube video which may help. I'm assuming you don't have satnav.
Do both front windows not work or just one?
Great pics! I'll add them to our Audi's from around the world thread :)
Cheers
