Seeing lots of questions on route and waypoint transfer. Quick suggestion: If you have a new Navionics chart, make sure you register for free Fresh Data daily updates and you'll see the opportunity to get a free PC App. If you download this you can transfer waypoints/routes. For example, if you go from Lowrance to Humminbird, download your waypoints to a blank SD card. Pop it into the navionics app and save them. Then go under settings and click save as and select your humminbird model then save to the SD card or MSD. you can then move the points to your new Humminbird.
