I've a 2013 A3 with a Tech pack retro fitted by the previous owner. The Satnav works but the parking sensors (orig) don't display on the screen but do sound.
I'd like to;
Get the parking sensors to show on the screen.
Add a rear camera.
I've come across a comment that you know a UK guy that can apply the reqd coding to the units, could you let me have his details?
Cheers, Ian T.
