Has anyone tried to connect the GP1870F to a minnkota iPilot? I want to be able to navigate from spots saved on my charplotter using the iPilot and then use the anchor function to stay in the same GPS position.
Unless a user has something to offer, you might want to try the manufacturer MinnKota. Looking on the internet it appears it only listen to a propriety I-link communications.
Maybe they make an optional NMEA2000 interface.
