Project was abandoned Silent Thunder
Wanted the OEM/Stock look of the Mc back in place and the HU in the cubby space (like the OEM sat nav) so more at eye level. That was the main aim but cost of fitting a HU to the space provided was too much so decided to call it off and cut my losses. I also liked the appearance of the car pc type screens in the cubby space from the various builds on here and noticed that these screens needed no modification to fit - I already had a pc and all the parts so thought about pursuing this project because the only extra bit I would need was a screen... and it was possible to do with a bit of help from other members (thereby saving costs that way). The android idea came into it from conversations with guys on the legacy gt forums - some had abandoned the pc because it gave them too many headaches tweaking it and said the android system was easier to use and the 7 inch screens fit nicely.
But you're right some of it was feature creep and I decided I would hardly use those features so aborted. Plus, Clarence also made two good points - the distraction of the brightness of the screen in the cubby (I'm sure you could tweak a pc to adjust automatically but I didn't really want to stuff around with another pc project [have 2 pojects at home already!]) and the head unit is easier to use lower down. Plus I rarely use the gps so the few times I do I can put up with looking slightly down every now and then. ie potential features didn't outweigh the cons sufficiently. So sold the parts - made a loss but I think I would have thought about this for a while if I didn't give it a go. Live and learn. Funds going towards a short shifter instead

.
Nevertheless - anyone who wants to put a double din HU in there; it will fit but will need some modification to the available centre consoles with either a frame or bog and paint to make it look good. I just couldn't find a cost (and time) effective method of doing it. If my DIY skills were better I might have pursued it for longer! Anyway, long post but hopefully others can gain from my experience with their projects.
