I have Pandora iPhone version 3.1.3, plays fine on the iPhone - no problems. But, When I put it on m X920BT (firmware on the Pioneer is new 2.0003 ) with 3G connection I don't see the album art and none of the touch buttons on the screen are active (x920BT). The iPhone displays the "hook-up" screen. I do get sound though. I tried Wi-Fi from my garage and still no album art of hard ware. I've go higher quality audio turned off. Thoughts?

Are you using the original CD-IU50V Pioneer cable?

Good idea, that may be it.

I ordered the cable from newegg.com and everything was the same including the cable name, it has worked with the the Pioneer AVIC X920BT in all other functions.

But, I suppose in a legalistic sense there could be an issue with the Pandora link and that particular cable.

Thanks. Don't know that I'll swap the cable just for Pandora - but you could very well be right.
