Thanks VBlue -- helps a lot.
Anyone know why Pioneer chose the 17-pin USB cable option in the x8500? They make it appear required, but if not, what is the purpose? For one I can see it would add a second data port, in addition to USB1 -- that in itself is useful info if true. I can't imagine in the engineering scramble to address apples lightning port 'enhancement' that they decided to add a 17-pin proprietary port simply to be able to charge $50 for it. Does it provide more power than the USB1 port (say to charge an iPad)? Or does it really add nothing except an additional data port?
Also, does anyone have a shot of the back panel of the x8500? The manual doesn't really give a good representation.
The only advantage then of paying for the x8500, to me, seems to be the digital video options / android support -- HDMI in, SD card, 2nd video out, etc. Is it worth the extra $$ over the x5500? Prob not, unless anyone has strong opinions on if the x5500 DVI->VGA cable / required firmware upgrade will be inferior to the HDMI cable option of the x8500. Will I still have two data ports on the x5500 (Adapter + USB1), or just one? Seems you can have up to three on the x8500.
