I understand that the Streetpilot tracklog can hold 500 points (bread crumbs). How often are the points dropped?
would like to know which method is being used (Resolution, Time, Distance, Other) and a little more about how the chosen method works in the case of the Streetpilot. My experience this past weekend with the track log on was that on a fairly long trip the log was used up and the new points began pushing the older (beginning) points out of the log. So the effect was metaphorically like my car dragging a long piece of string behind it. How “long” (in time or distance) can I expect the string to be? Answer: The StreetPilot track log is set to resolution mode with a track deviation threshold of 50 meters (the GPS III defaults to 25 meters). This means that if you are traveling along a road and your actual track deviates from the straight line track projected by the StreetPilot by more than 50 meters, SP will log another track point and project another track along the direction of travel. The track log recording is a little bit better than what’s in the III – it doesn’t round off corners as
