When I go out for a days walking, I often get a bus, walk for a while then get the bus home, or to another point and walk a bit more. When I get home and switch the unit on my GPSMAP 64 has recorded a straight line from where I switched it off at the end of my walk to my home location where I have swtiched it on again. It also shows straight lines between different sections of a walk where I have switched the unit off, got on a bus, then switched it on again when I start walking. I want to be able to see just the distance I have walked not the travelling between on my Trip screen. How do I set the GPS unit to do this? My old GPS 60 Unit only did this every now and again and only between the last walked point and my home location. It never recorded the distance between different walk sections. The map screen would also show my walks as disjointed tracks. I really want to be able to do this on the GPSMAP 64. But how?
