I also purchased the digital download for my Garmin Edge 1000, which I am slowly getting accustomed to.Great choice. The Edge 1000 is a superb device. Review the detailed instructions for loading routes onto the unit.
Does this sound about right. Not sure how the 200 waypoint limitation comes into play.Yes, what you have done is great. You are good to go.
The limit of 200 waypoints is for services along the route. These will work far better on a mobile device per Jennifer's note earlier.
