Sorry to resurrect and old thread, but I've been searching for an answer. I had my Z2 professionally installed about one month ago. I'd been using my iPod since day one. I had to replace the battery to my car and lost a couple of things when the power was disconnected. I lost my backup camera, but figured out how to re-initiate that. Now, if I plug my ipod in the ipod connects (I can see the Pioneer logo on the ipod, I can see the songs and browse the ipod on the Z2) but there is no sound.
I checked the sound on the Z2 and it looks good. I checked the sound on the ipod and it's turned up about half way. I experimented by turn the ipod volume all the way up and all they way down. There was no difference.
Can someone help?
