You rock

So I need a whole lot of other parts before I start! is there a list of part #s or should I go by the pictures?
My email address is

Also, today I put in this peculiar head unit that is apparently an early version of the nav CID. It works fine w/o the nav computer, but of course doesnt have the navigation function. The screen can display temp, speed, radio station and some other info. So far I am favoring this over the regular CID because I have not used the CD player in ages anyway (Mp3 + AUX) and a small screen can be useful when the top screen is closed. What do you guys think?
