After using a Lowrance that I liked (died and no new maps) was on the Garmin for a short while (it too died!) and a Chinavasion (also died!) so I seem to be pretty good at killing these things!
Now playing with a Kyocera DuroForce Pro cell phone with Osmand+ (less than $120 invested) for my GPS. Waterproof, somewhat glove-friendly, wireless charging or 2 point contact charging. Screen is MUCH easier to see in sunlight than the CV unit I had.
Got a Verizon version so it can be a backup to my other phone. Connects via bt to my Sena. DL'd all maps so it works "offline", no data charges.
Still learning the software for creating routes, but it is very promising!
