To download gpx to any Lowrance GPS, use ExpertGPS gps mapping software. Download GPX files to waypoints, routes, and tracklogs on your Lowrance GPS receiver. ExpertGPS uses GPX as its native format, and has no problem reading GPX files that were originally created for a different GPS receiver. ExpertGPS handles the differences between Lowrance, Garmin, and Magellan GPS receivers, so that when you use ExpertGPS to download GPX to your Lowrance GPS, you get perfect waypoints and tracks on your Lowrance. ExpertGPS was written by TopoGrafix, the maintainers of the GPX File Format Standard, so you know you're getting a proven GPX program.
When you use the software from your GPS manufacturer to manage your GPS data and download GPX files to your Lowrance GPS, you risk getting locked-in to a proprietary program. GPS technology changes all the time, and Lowrance uses MapCreate to keep you locked to their data format and line of GPS receivers. By choosing ExpertGPS as your software to download GPX files to your GPS, you're ensuring that if you switch brand loyalty in the future, you'll be able to transfer all of your existing Lowrance data, and you won't have to learn a whole new program to work with your new GPS. Plus, ExpertGPS is tailored exactly to the capabilities of your Lowrance GPS receiver. ExpertGPS will even warn you if you try to send more waypoints or track data to your Lowrance GPS than will fit in the GPS receiver's memory. That's why it makes sense to download GPX to Lowrance GPS receivers using ExpertGPS instead of Lowrance's software.
