Hummingbird links to Minnkota, Lowrance links to Motorguide and Lowrance Ghost, and Garmin links to Garmin Force. Not sure about any of the other myriads of networking. I put a Lowrance Hook Reveal Tripleshot on the little boat I bought last fall and run the Navionics card in it. Really like the unit, very user friendly. Have a Raymarine unit on my Pontoon and the real3d is great for mapping out ledges, rocks and such as you can spin the image in all different directions in real time.
