I read and followed the links on various pages about accessing the hidden equalizers on the
audi symphany system
power off stereo, turn off car, remove keys, power back on the radio whilst holding in the 5 preset button, but no joy
another site had the same process, but hold in the 1 and 6 preset, still not luck

Anybody else come across a different process?
