Thanks for posting this, I’m curious to see as well as I would love to add this feature if it’s available. My current GPS tactics involve walking until the 37th tree on the left with the birdhouse on it. It would do me some good to get with the times.
Navionics. Totally worth it. I’d also recommend the $5 upgrade which gives you more features and customization options. I’ve found it to be pretty accurate for the lakes I’ve been on.
