I have to believe you can make a rather complex along-road route (maybe not walking) with 50 via points.
One trick I used when I had zumo's was to use waypoints for information and not route path shaping. This enabled me to have lots of Waypoints associated with the route. I used Proximity Alerts so that I would get prompts on the zumo.
You are likely right DRTBYK.......only I have become so comfortable with the ease of track use that I really only use routes in a pinch to get somewhere quick without spending a bunch of time figuring out an exact track.
