Thread: what are my options for a motorized in dash screen? and a few other Q's?

i have searched and kinda need an honest opinion.
want a touch screen. the screen would be used for dvds, music, and navigation. primarily navigation since i want to use my alpine deck that i have.

heres a few on ebay.

hvn't really found any sites with these monitors besides mp3car.com and digitalww.

also my next question is this. my alpine deck has a input in but as far as i know its only 2 rca's. my question is since i have front component speakers running off an amp and the rear speakers are still running off the deck, how does the computer process the fronts and the rears? im really kinda confused on how this would work because i would not like a sacrifice from my set up i have now.


so if any one could shed some light on these questions i would really appreciate it.
