I purchased the original Pioneer CD-IU51V and plugged it in and plugged the iPhone 4s in. I got no sound I switched the unit to wired and still no luck it does everything but sound. You canBT it in and get sound, but no sound on Ipod music, Pandora, or aha radio. It shows it's playing but no audio I unplugged it and plugged it back in and still nothing. I could not find anything in the manual either. I read somewhere on here that you need to turn off icloud share but I don't see that anywhere on the phone. If anybody could help I would greatly appreciate it.

Don't know what I did, but I tried my old iPod and it worked then I plugged the 4s in and it now works. I just wish when you used the Sirius app on your phone it would show on the screen oh well you can't win them all.
