Ray,
I found your post through a Google search. We are using a fairly expensive commercial system (h/w and s/w) to record GPS signal on the audio track and then view & process the video with a synchronized map “live” at the office. It is quite an expensive system and I’ve been asked by clients to see about any cheaper alternatives. You mention the cost of $400, could you perhaps post a link to the vendor?
Thanks a bunch,
Andy
