I used my phones internal gps receiver (Nokia 5800). I think it is 1hz, but not really sure. For more professional setup, I'd look up an external gps and use OBD channels too (if available in your vehicle). My setup was more like a proof of concept for my future setup :-)

Nice video!

What kind of gps reciever do you use? 5 hz?
