This is my inclination; especially since plans WILL change as a function of timing, weather, advice from fellow travelers etc. I have a lot of distance to cover and might have to cut some stuff along the way if I can't keep to the schedule.
I have a lot to learn with this so I'm hesitant to offer advice but, with regards to above, I've run across the same scenario. Plan a trip out then deviate for whatever reason. Never recalculate and find myself back to the route by however. But, if you should turn off the GPS or
stop the active route and then wish to go back to it, it will ask you where in the route do you want to start from or what is your next waypoint. I have found that if I do not simply/clearly label my waypoints in BC, sometimes I won't remember what it points to on the route. For instance, a waypoint inserted and automatically labeled
4N Ramp might be better labeled
Anytown Rte.4 or something to that effect.
The tutorial was great Ed. I've gone back to it once or twice also.
