I have a 2004 Volvo XC70, it has a GPS system built in... I would rather use it as a media / music system / GPS etc.. Below is a link that someone started, but I think you & your team might be better at this... I am really new (trying to get started) with the whole RaspberryPI / micro controller "hobby" http://wot.lv/raspberrypi-powered-car-pc.html
