I finally got my HU back up and running and now when I have my iPhone 3gs plugged in to my cable (pioneer) the volume is stuck and I cant turn it up or down. I also tried using apples cable and I get no audio whatsoever. I tried reconnecting all the a/v cables and I made sure the input was on ipod. any fixes for this? anyone come across the same issue?

I have a similar issue with my iPhone 3GS and my F90BT. Everything looks great and the song is playing, it just has no volume.

Ipod that shows on the screen but you don't hear anything is usually:

A: You didn't change AV1 to ipod

B: You're using a cable without RCA jacks

C: You didn't hook up the RCA jacks on a cable that has them
