There is a device to do your navigational stuff, you may or may not have
heard of it, VDO Dayton. Depending on the model you get, you can have
on screen realtime updates of your vehicle's position (via GPS) and I think all
models offer voice cue's for directions. AFAIK the screen is able to be
connected
up to either PC or composite video also so it may fit in nicely with your idea.
The price isn't too bad either, the model with vocal and visual directions only
with no map display is about $2500AUD, the model with the full map display
screen is
available here in Australia for about $5500AUD. That's a lot for me, but
the price sounds a lot nicer in US currency :)
