Ok this is what i'm looking for.

In dash (Single din) lcd touchscreen flip monitor with radio (possibly with connections for a reversing camera)

I would like the carputer to fit in a spare din slot i have but its not neccesary, i can fit it in the boot if i have to (just thought it'd be easier in the spare din for connecting the speakers)

at least 80gb hard drive (for all my mp3's, movies etc..)

Windows Xp

I'm looking to have the playnow bios or whatever its called so you can play dvds etc... without having to boot up windows.

I want to be able to connect to the internet via wireless (to check emails in wifi hotspots etc..)

GPS

Car diag system.

Being able to hook up to my mobile phone.

The auto start up/Shut down when the ignition is turned on/off

I've gone onto Car-PC Shop for car computers ! and built this. Let me know if everything suits my needs (bar the software) and fits together and if i'm missing anything either
