I've seen a few posts that suggest that the F series are alot like Sync technology. Well the sync technology is compatible with the Zune. My question is of course, does the new F series feature compatibility for the Zune? Maybe through USB at least? Man that would be sweet. I loathe ditching my high dollar Zune 80gb when its been so good to me. I mean other than the whole car head unit compatibility thing its as good or better than the Ipod, but you dont have to deal with iTunes.

No. The voice recognition only works with the ipod and phone functions. The Zune will only play on the unit through one of the two AV inputs and you have to use the Zune for control. There is no interface for it on any of the Pioneer units.
