So I got a bit bored when I was studying and these are the results...
Ever wanted the 2010 Audi A7 Google Earth system in your car?
Live positioning and tracking in google earth offline using caches i've scanned over then backed up to areas (2g limit).
First played with on my desktop (grunty pc), now have on a cheap netbook which is portable(em350) running smoothly.
Garmin map60csx --> GpsGate --> Earth Bridge --> Google earth.
Running on 32bit XP and 64bit Win7.
Garmin is usb into the pc.
GpsGate emulates the com port you would get from a serial cable.
Earth Bridge sends all the right data to GE and is easy to tweak (height etc).
I'd upload pics and vids but i've blown my bandwidth for the month sadly!
Any questions please send them my way or just post on here. It was hard to find this info so
hopefully this helps someone out
Should be easy enough to setup with nearly any pc or gps as far as i can see.
