I've got two Helix 10s on my boat. Helix 10 SI gps gen1 on my dash. A 10 gps tied in with ethernet on bow. I have a Ulterra self deploy min-kota with I pilot link. I'm really interested with the Gamin liveview but know nothing about Garmin. What Garmin monitor do I need to get? I think 9 in is as big a you can get. Can it be mounted to the ulltera or is it better mounting it different because of spot lock? I appreciate any opinions or ideals.
