I wanted a gps for my Landrover but couldnt find one with a big enough screen , so i decided to build my own
.I rebuilt the center console between the seats making it slightly larger and incorporated a computer in it (athlon 1.2 , 80 gig hd, g-force 2 , 512 mb ram , dvd player, wireless network card, serial gps reciever). The computer bits I had anyway, the screen ( 10" touch ) bought off ebay for £70.. , the garmin gps 35 series came from maplins ,and the wi fi ariel is a d-link
http://www.dlink.com/products/?pid=56, For the gps tracking i use m$ autoroute 2002, which is good in larger cities but sadly lacking in detail in rural areas especially southern ireland. The whole set up is powered by a 800 watt invertor ( turns 12v into 240v) had a few teething problems at the start with power consumption but discovered that my split charging system (2 batteries)was faulty. With that fixed everything is running sweet, I got 30 gig of tunes stored on it (5.1 surround sound) a few of my fav dvds ,couple of games... net stumbler, etheral etc , a complete in car entertainment system, all i need is a pci fm radio reciever to complete it....
Attached is an image of the screen running auto route on a recent trip to Wicklow
