Do you want Seatalk to NMEA 0183 conversion on your DMK Box? Swapping out the main board inside your DMK Box will enable this conversion using the apps iRegatta and iNavX if you have a Raymarine ST60 or ST50.
To start the process of a free swap, email firstname.lastname@example.org. You'll receive instructions on what to do next.
After you get your instructions in email, visit this video for further instructions on how to replace and exchange the main board in your DMK 11A or 11A-GPS.
