I have the F910BT and every post, every accessory, update... refer to he 90 or 900, not the 910. I forget the differences since I got mine. I know there was a "Premium" and something with pre amp outputs as well as iPod cable.

Is there a page describing all of the differences?

I goofed, sorry. I have the F90BT (premium) with hi volt ouputs and it came with iPod cable, and the 910 is the X910BT, not F910BT. And I think the X910BT is the source for the 3.x firmware, correct?
