which screen

i have to pick which screen i want to put in my car.

the first is a poineer avh p 6500dvd.
it has: 6.5" motorized widescreen touch panel display, dual zone ready, mp3, optical out, 26 pin rgb input, triple 4 volt preouts, and an on screen display

the second is an apline iva-d900
it has: 7" widescreen motorized dash, xm ready, 50x4 triple preout with 4 volt sub, navigation and rear camera inputs, 3 aux a/v inputs, trizone a/v control, mobile hub link.

i want good sound/video quality which is why i prefer the alpine. BUT i love the idea of the touch screen from pioneer which seems to be very close and a lot cheaper. they are both good products but i don't know what to do.


what do you guys think
