Question: Alpine IDA-X303, Ipod connects but no sound

My son bought the Alpine IDA-X303 radio and had it installed by Best Buy. His Ipod connects so you can use the radio to control the Ipod. However there is no sound. We rebooted the Ipod and that helped once, but again there is no sound and rebooting is not helping. Have you heard about this problem? Would appreciate any help you have. He just got the radio last Sunday, and is very frustrated.
