Putting an audi sypmhony in transport mode?

I am selling a Audi symphony radio and need to ship it. I was wondering how do you put in transport mode?Putting an audi sypmhony in transport mode?As long as there is no power to it you shouldn't have a problem. Pull the fuse out of the back and ship it with the radio. The next customer will have to have the radio code to make it work though so if you don't have it then he will have to use the serial number to get the code from a dealer.
