Radio Code!

WTF...is a radio code.

I pulled the radio out and disconnected to get to the turn signal relay switch witch I guess is the Hazard button. Anyway I called the dealership and they say something about a radio code and charging me $135.00 You have to be kidding me WTF is that? Hell I'll put a better system in with $135.00 and more.
So is this correct I need a code! If so can I get it anywhere else cheaper.

Any help! and oh! yea they are charging me $60 bucks for the switch I think that is a little high as well.

I called Eric at Champion and the code was listed on my owners manual and I blew a fuse. So one thing leads to another. Thanks Eric and Thanks as well Sito at
Coral Springs Audi. Thanks fellas!
