Using an Autohelm 4000 how do you connect it to a GPS?
This boat has a Magellan GPS and will have a Laptop running whatever NAV software this setup will require. The Idea is to be able to have the boat travel a route as programmed into the GPS waypoint by waypoint. if the PC is not required great!


Looks like it’s not made to interface with GPS.
We have an older Magellan GPS (Meridian XL) and it interfaced beautifully with our Autohelm 2000+. We have an Acer Aspire laptop (w/Cap’n Voyager program) hooked into the system as well, which we use as a chartplotter, but it is NOT required for us to navigate point-to-point as the GPS transmits data to the Autohelm in the NMEA 0183 format.
You’ll need a power/data cable from Magellan to get it done.
Good Luck
