I would love to save a couple of hundred dollars on the AVIC-F900BT but if it means losing warranty so I would rather wait. My question would be "Which is the cheapest authorized dealer to buy from?" I heard about all the issues that people are having with the unit http://www.engadget.com/2008/06/17/is-y ... acting-up/

Are these the kind of issues that can be fixed via a future update ?

I know the difference between the f90 & f900 but if I dont have a subwoofer does the preout voltage that important?

Anyone know if this unit works with the iPhone?

Final question: Can I connect 2 headrest screens to this unit?
