The sequence of programming for 2000 Audi A6 radio is:
1. Push simultaneous "SCAN" and "RDS" keys until on the screen will appear "1000" displayed.

The radio is now ready for use!

Do you have the code? do you have the owners manual? if not, just go to the dealer, they may have to remove the stereo to get the serial number. There will probably be a charge, although sometimes it's done free. If you have the code but not the manual, here's a link: http://www.ibiblio.org/tkan/audi/radios/symphony.html

The radio code is only obtainable from an Audi dealer. They would have to e -mail Audi with the vehicle details and the radio serial no to get the radio code. They would then enter the code for you.

You will need the code to get it working. You may need Audi for this. Never disconnect the battery, or the alarm with trip on. Since it is frozen, I would try and remove the fuse, and reinstall it to reset the stereo. Then try the code.
I got lucky in my 2001 VW passat, when the stereo code was needed, but then the next day it started working by itself.

you will need to pull the radio out and get the serial number off the back of the radio unit. then call up your local VW/AUDI repair shop or dealer and ask them to look up the code for you. i had to do this last week with my VW jetta.

try another dealer. maybe try to get ahold of one of the techs at lunch time. this info should be free to the car owner, just be ready to supply the title to the car for some proof. maybe try buying the parts guys lunch or coffee and donuts....this usually works for this type of problem. unfortunaley this info really is dealer only..

hold rbds and pscan till you see numbers then use the radio memory buttons to control the number you want to put in after the numbers are put in hold rbds pscan again till u see it says safe and radio works.

I just posted a solution for this problem. It comes straight from the radio manual. The dealer should have told you this. If you want him to do it he'll charge money for his time. IF YOU LOST YOUR CODE. THE DEALER CAN HELP YOU OR IF YOU HAVE YOUR 4 DIGIT CODE:
