Had my coupe for about a month.Gradually working through my list of things.

I am wondering if the head unit is coded wrong. If I try to set the fader control it says it's "off".

Anyone know what the correct coding would be?

It's really a 3 channel system with rear "fill" only..

You can re-code to turn the Bose equalization off, but still no fade...

My 96 A4 had Bose and the Fader control worked. Even when I replaced the original Delta stereo with a Concert, the fader control was still operative.

The HU has the capability, the Amplifier used does not.

On the A4 there's an additional amp in the trunk for the rear deck speakers.
