having the same issue as everyone above... I've tried multiple iPods and IPhones to a varying degree of success. I did have the problem before updating to 3.01...
To date, this is what I've tried:
- swapped cable with Monster/USB cable - no change
- updated F700BT to firmware 3.01 (needed to update maps anyway) - no change
- downgraded iPod to firmware level 1.1.1 - no difference
- contacted Pioneer - predictably, NO DIFFERENCE.
Pioneer's answer is "send it in and include a $200 check if it's out of warranty" because the warranty on the unit only supports shipping it to Ohio. Horse hockey.
There are times where if I reboot the iPod (menu and middle button) and restart the unit enough times, I'll get the first song to play but as soon as I select anything else (another song, playlist, etc) it barfs and disappears. I've spent the last 4 frustrating months trying to solve this and if I'm certain of anything, it has NOTHING to do with the cable you use (swapping it might solve other issues, but not this one) - this is issue is solidly a software issue between the AVIC and the iPod.
To make matters worse, if a number of others are having the same issue, I am fairly confident Pioneer will not be able to fix this issue if I send it in.
Ah well.... off to call the warranty dept. I'll let ya know what I find out.
p.s. - funny, I went to my local Apple store and asked about downgrading the firmware on the iPod and while there mentioned why I wanted to. The guy there just smiled knowingly and said, "yea, I get that a lot from Pioneer customers". Ominous...
