I have searched and searched, and have found somewhat conflicting reports. I just purchase a F90BT and will the new iPod Touch Second generation work with head unit? Specifically will the head unit be able to control iPod Touch Second Generation?

I doubt there would be a problem. Runs the same software as the previous model. Can't be 100% sure for you but, I don't think there would be a problem.

I have the 900 and a 32gb touch and it works perfectly.
