True, but that would be contrary to what Pioneer has done since the inception of the AVIC line. The software that came on all new models in the N, D, and Z line were easily installed into the previous models. It would be the exception rather than the rule for Pioneer to just do a 180 now and not allow this. I feel very strongly that when the new F units come out their software will be very easy to install in the current line, like it has been all the way back to the N1. Of course there are no guarantees, but I would be shocked if the new software is incompatible with the current line.
