What really chaps my behind is product is shipped not up to date I install it. Contact hummingbird too ask why I cannot get them networked and they say oh it’s because you don’t have the right software. Mind you I had it for two days before this call. Lakemaster chips worked then. Update to 2.0 now it does not work. Cannot get Humminbird on the phone. And have close to 10,000.00 dollars of their product on my boat that doesn’t work. Not like I bought the cheap stuff. Oh and by the way went fishing tonight and my si unit stopped working and I had to unplug it to get it shut off. Monday is gonna be a day of reckoning.
