If you have the original documents (owners manual that came with the car) there should be a anti- theft "code" with instructions for unlocking the radio. If you can't find this info from the factory owners manual - you have to go to the Audi dealer for the fix

Get the code from your dealer with the car's VIN if the system is OEM. Chances are the code is somewhere in the owners manual package that came with your car....so much for theft proofing...if you or the PO haven't removed it.
If you have the code, like 0095, you press and hold two buttons on the RHS of the Bose Symphoney II, the PSCAN and RBDS buttons IIRC for about 3-5 seconds...the SAFE should go out and 0000 appear on the screen. You then use the first four program buttons to cycle each number (1 for first 0, 2 for second 0, etc.) to the program code. When you've entered the program code, press the PSCAN and RBDS buttons again to start the radio. I don't think the ignition has to be on.
Next time use a battery jumper...I prefer the portable kind that can be recharged through the power socket/lighter. I just replaced my battery ($153 genuine Audi OEM vice $300 installed) and had no issues with the radio. BTW, the auto up on the drivers and passenger windows probably has to be reset. Lower the window(s) all the way, raise them up and HOLD the switch up for 3 seconds...the auto up will reset.

That normally means that it requires the  security code to be entered.

Disconnect the fuse for 10 minutes, replace then enter the code.

If you do not have the code then the radio will have to be removed from the dashboard and quote all the letters+numbers on any labels, barcodes or stamped in the metal casing.

Also quote the make of car it is fitted into.
