Thanks for all the information on the OSM maps. I am going to purchase a micro SD card and try downloading some maps. Makes more sense than paying for the Garmin maps as long as the OSM maps work, and from what I see here and other places on the web, they seem to do the job. On the start stop issue, from what I've seen, there is a pause feature so when you stop, it stops. When you start up there is a prompt asking if you want to resume timing, you press yes and off you go.
