is this a brand new car? stating the obvious but have you turned the volume up on the dial (big black knob on the sterio) press and hold it in to turn the radio on or off ??
=you should see "volume" and a number if you still cant here anything by the time it gets to 10 you could be deaf or it could be that they havent pluged in a multi (big) plug on the back of the sterio unit...
