Do you want to:
• create or enhance a route that will be more stable on recalculation?
• import from Rever or Google to Garmin with stable results?
• switch between via and shaping points without name or location changes?
• share a stable route so that others can recalculate reliably on their devices?
• enhance an existing route so that, on your device, it better follows the original track?
• create a stable route from the waypoints and track someone shared with you?
• create a track and waypoints from your Garmin calculated route? (maybe to share with others)
