individual to the radio.Each radio has its code from the factory.The only way I know how to get one is to see if the dealership can run your vin to get the code(provided thats the same radio that came with the car new)

would you happen to know if it is individual to the car? or if there is a default code?

the code was in the owners manual when I got it

How'd you get the radio code for your premium 7? I'm planning on eventually selling mine, but I bought the car used.
