Wiring the Standard Horizon GX2100e to a Garmin 451s
I've wired it up according to this diagram:
Not getting any position/time shown on the radio so not convinced they are communicating.
I have been, however, setting up in a garage and the garmin hasn't found a satellite (flashing ? over the boat)
Could this be the reason nothing is being passed to the VHF? I'm not sure as the Garmin is displaying a position albeit in the wrong place in the USA.
Any help appreciated.
