Seriously guys, the PC (vga) screens arent transflective like your factory satnav screens, pdas,phones etc (its a kind of coating that makes it readable in sunlight i believe) so in brigh sunlight you will be dissapointed. MP3car.com do a modified screen in there shop

but it aint cheap. theres a nice video for comparison too.. should give you an idea of what to expec. i plan to upgrade to one after i have sussed my dbl din conversion. other than that look for a screen with decent contrast ratio - i would reccomend the same as after my research (for motorised anyway) its the best of the bunch. most of the other are much of a muchness. whatch out for the tat too. notice mine looks basic, simply becuase the others look chavvy / tatty. Its a enthusiast market so theres not alot of main stream kit availible.
I also had to make my own USB adaptor and VGA lead as there isnt much space behind the console - the tft hung out about an inch. see SamDudes Golf PC, looks like he had the same issue as it hangs out further than anything else. (be nice to know?!)
A friend has the liliput spring loaded (not motorised) screen with built in radio and to be honest it looks like an argos alba. nasty.
I did think for V2 on using a Pioneer/Alpine dbl din unit with RGB in, but you loose the computer controled touch screen, however i did think about making a BMW I-Drive type controller out of something - or even a rouch pad/laptop nipple on the door handle / steering wheel.
I didnt rewire, i ran some RCA's from the PC in the boot to the center console. and used a 410 RCA - Audi Bose harness adaptor, minimal work.
Im no massive car electric person thou i do have some knowlage, i picked up the IGN from the stereo multiblock (yellow wire with red stripe) and ran a feed to the boot.
Dave, i have a liliput TFT i used for testing if you want it cheap. its a stand alone one with a mount etc.
bout the same Quality as my motorised.
but what you really want for the dbl din is this
