How to import a .gpx file into a Garmin 765T to create a custom route

[routeconverter]

I think there is a way to (from a route or track) make a list of waypoints that are (hypothetically) say 1 mile (1.6 km) apart... that'd REALLY help if I could figure out how to do that using Route Converter...

Try this:

• go to the Plan tab
  
• click on 'Transform Track into Route'
  
• 'Select all duplicate positions within a distance of XXX meters of their predecessor' is the option you need
  
• type 1600 into the text field
  
• click on 'Select'
  
• RouteConverter tells you, how many positions are affected and selects them
  
• click on 'Delete selected positions' to delete them
  

Not that difficult, isn't it?

Would it help if I sent you the .gpx file??
