Pioneer Double Din 7850 DVD

[J-MuN]

there's no need for 6 mp3 cds when you have gigamp3

But there's always need for 6 disc dvds full of video clips.

is there any down side about this kinda touch screen unit? or other stuff that i should know???

Well obviously if it stuffs up, it's gonna cost a bit to fix but both alpine and pioneer are touch screens. More user friendly. My opinion, i'd go the Pioneer.
