Are there any clips that came with the facia, on the MK 2 focus (prevous car) it was basically the same as yours, but had 4 clips in each corner to hold the fasica and cage in.
Was the headunit exactly the same as the one above, or did you need 4 keys to get the headunit out?
EDIT: Sorry re-read your thread. I was under the impression you had the same headunit above. Its basically the same as the MK2 focus, there should be 4 'U' shaped clips included with the fasica which clip on (be careful as they can bounce off, or fall down the hole!) these simply clip into the hole. Put them on the fasica 1st (I glued mine on) and then push the fasica into the gap. I don't believe you will need to unscrew the above screws.
I would love to see Heads Up Displays become more common on cars, having common readouts on the screen, and also less analog dials and more digital. I have torque on my phone and its great having all the stats of the sensors etc, think that would be nice to have built into a system for the car.
Another good feature, for estate users that have kids. An extendable cover when you open the tailgate, to offer a good surface to keep you dry when putting buggies and shopping and such like.
