Just bought a new Elite 5 with the navionics maps package.
I have all of my marks on my handheld gps and obviously need to transfer them to the new sounder.
Is there a way I can plug the SD card straight into my PC and enter them from there?
Do I have to spend hours and hours sitting in the boat and entering them all using the unit interface?
I'm assuming because you can download your gps marks, you must be able to upload? Just can't workout how to do it?
