i think you can look at maps on your pc and mark GPS waypoints and then load them to your lowrance. and do you have it and do you like it?

Navplanner by Navionics?

Nav Planner and Nav Planner 2 have been discontinued. It has been replaced by the Navionics PC app. It can be purchased at navionics.com in the web store or you receive it free if you purchase a new Navionics chart for your plotter. You get the entire region of your choice for $49.99. It is updated just as the charts are now updated with the freshest data available.

The PC app is junk as it can only load a maximum 100 waypoints. Which means your entire library of way points from your unit has to be 100 or under or you receive an error message when trying to start the app.

I've written Navionics about this numerous times with no response from them other then Sorry we cant support your request.

The PC app has no value to me.

thanks guys
