 The picture given below is that of PC that I installed in my car(year 2008), when tablets where not that common. 
				   The heart of the PC was an Intel D425KT motherboard that comes with a 1.6 Ghz dual core atom processor
                    and 4 USB inputs. Added 2 GB of RAM and 80 GB of hard disk. For power I used a 
                    160W 8V-28V DC-DC ATX MINI-ITX Car PC Power supply purchased from ebay. Enclosed
                   all these into a cabinet from thinPC.co.in.

                   Mounted a 7" touch monitor onto the dashboard. Plugged in a bluetooth receiver and
                   paired the same with a bluetooth GPS receiver. Installed Windows XP, 
                   Destinator 8 and SatGuide maps to show India maps.
