I have a ghost coming and am planning to install myself. Boat is a ranger 620. I have watched a couple install videos and I have a couple questions:
Will I need a lowrance point 1? I understand it can be better for the waypoint/gps on the graphs but is it necessary for the TM too?
Do I have to have a NMEA2000 system? if so what for?
Happy to buy both but just curious if I need them or if I can get away without them. I should probably have a Point 1 anyway to line up waypoints better but I'm inherently lazy and don't want to spend the money on a little piece of round white plastic (I know there is more to it than that).
Thanks all,
Zach
