Supports Only Garmin

When I first got this app 4 years ago, I paired it with a Dual GPS "puck". Worked beautifully for pre-trip charting and following along in real time. Then Garmin came out with their own mini GPS and they suddenly disabled external GPS support....for anything but Garmin products.....and their support says it was never intended as a real time charting app, bit there is a button for external GPS in the app...which clearly worked before. I will be going back to Navionics since they dont play hardball with the GPS you use.
