Only thing I can see is the Preout Voltage. Does anyone have anything else?

I can get a real good deal on the AVIC-F900BT so was curious if it was worth saving the money and getting that one over the AVIC-F90BT

The f90BT also comes with a two year warranty instead of the one year warranty on the f900BT.

Yeah I noticed that too... but feature wise, if I can save a couple hundred and not worry about the extra year warranty I will do that.

90 comes with ipod cable 900 is optional so thats another $40 bucks for the cable. How much you find the unit for? 90 and 900 should be around same price.
