I am upgrading my boat to include a Motorguide Xi5 trolling motor networked to my Lowrance chartplotter. The trolling motor should follow routes from the Lowrance unit. I wish to create routes on my computer using Reefmater or Reefmaster generated AT5 maps. I have not found any features in Reefmaster that would help (yet). I have Insight Planner, but it seems the route locations change with zoom which does not instill confidence. Any help??
