This item was removed from a vessel during a refit.

This J300x course computer is in great used working condition.

PLEASE NOTE: When installing a new-to-you Autopilot Junction box, it is imperative that you perform a factory reset and go through the dock-side settings to set up the Junction box for your vessel.

It has been fully bench tested for Both NMEA Inputs, Both NMEA Outputs, rudder input, heading input, controller communication, and motor outputs.

The autopilot display is not included.

The autopilot screen (not included) shows AP engaged, the Standby screen shows rudder and compass functionality, and the pictures are of the unit – every picture here is of this unit running. We don’t believe in stock pictures.

We tested both NMEA0183 ports with a Furuno VX2, which can be seen on the port monitor page. (VX2 not included)

This is not a complete autopilot, you will need several other components, this is just a replacement J300X course computer for the above systems.

This is compatible with AP20, AP21, Ap35, and AP22 control heads, as well as the AP3000x and AP11 systems. This can be used as a full-function replacement for the J3000x, the difference being the J300x has one extra NMEA in and out and has a higher amperage rating for motor current draw (basically it’s a more heavy-duty unit)

Guaranteed to work on arrival. If you’ve got a downed J300x or J3000x computer and need to get back up and running, look no further.

Please refer to the photos for item’s condition. This is a used item and may show signs of wear.
