Talked to Jason at True Heading, he's shipping an adapter out. No problem, plus i get to keep the cable for SW updates or if i ever want to convert it to Nmea 0183.
So after having offset problems with the N2k adapter the compass is now up and running, on 0183. While the sales support for True Heading is good they're tech support sucks, that being said I used Hemisphere for tech support who actually manufactured the unit and they were helpful. So if one decides to buy one, get a hemisphere version.
