I am trying to transfer my waypoints from my Gen 1 Helix 10 to my Gen 4 Helix 10. I'm using an empty SD card that has been formatted. After exporting my waypoints and routes to the SD card the Gen one unit says it has successfully done so. However when I turn on the Gen 4 unit I get a prompt saying that the SD card was successfully "encrypted". But when I go to look at my waypoints there are none there. Where am I screwing up?
