I have a Touch with the 2.0 software update. Has anyone used this with the Pioneer DEH-P7000BT car head unit? Crutchfield.com only lists versions 1.1.1 as officially compatible, but I've read of iphone 3G users saying theirs works with the unit, so shouldn't an Ipod touch with essentially the same software? By compatible, I mean the head unit recognizes, charges, and lets you control music on the head unit via the USB connection. Any help or experience would be appreciated.
