BMW X5 Radio Issues

[bunchi]

Hi, I can turn on the radio and change stations. However, there is no sound.
Batter was dead for some time and I had to remove it to get it charged.
What should I do? Do I need to take it to the dealer to get it re-programmed?

thanks

Could be numerous things like blown fuse in the radio to a loose wire but your probably better off on an X5 forum looking for remedies for it than a 10year old 3series forum.
