I kind of already covered this a whille back over at RPS i assume your talking about this radio
the measurments for it are
* 4 3/4 " high
* 7 1/2 " to 7 3/8 " width
* 7 3/8 " deep
yeah it wont "plug and play" and to get it to work you need an antenna, unless you get it from the donor truck your dead in the water.. your local ford dealership CANT order them for some reason or another the only way to get it is through a Europian Ford dealership..
The Ford Part number for the antenna is 1S7F-18A886-A4 For those who are interested, this is an HRS GT5-1s connector manufactured by a Japanese company called Hirose, so you could possibly make your own...
BUT.... (now for the good news)
i did a little searching around and found some VERY VERY valuable info...
first off ford doesnt make any of there radios... a company called Visteon does.. and if you go to there web site you can see that there is a differant nav radio pictured there... they have the VRN9000 pictured.. which is the nav radio for europian(sp?) states BUT if you could get ahold of one it looks like it might fit better if not "plug and Play" and the software is all one one disk, must be like a boot disk of some kind.. all you do is buy the one for your area, i am guessing they have one USA disk.
heres the back of that vnr9000
