1) Because of my discounted prices I have the installs done at RKST
2) No clue... I don't have the rear camera didnt find a need in a car that small
3) GPS = front right dash board... you barely see it cuz its so small
4) I dont like CD changers... I just keep a folder of DVD's + CD's in my console next to me...
5) null
6) From what I've heard it comes with it all there pretty fast and easy install other then the gauges thinger... that was a key reason why I didnt wanta install it ... cuz I didnt know what to do with that...
7) You can move the screen around up and down... to get it perfect for your style... Distracting? ... only if you got Pr0n running lol...
8) Hum... the beeping... you mean when you press the buttons... I havent tried to they are rather small and if your watching a movie it isnt going to beep at you...

I love this unit.. I looked at all the other ones first... I check out the sweet force feed back ones where you touch the screen and it reacts to your touch.. but its clarity cant compete... you need this unit in the xfire cuz of the gauges! its so sweet to watch yourself pull over +10 angular velocity on the guage... and try to beat it the next time around .... its almost like a mini video game but with your life at stake! its uber sweet!!!
