I suspect that your new autopilot uses NMEA 2000 (SeaTalkng) so check out the Actisense NGT-1 USB for NMEA 2000 to PC interface. It is compatible with the latest version of MacENC. (The devices you listed support the older NMEA 0183 and SeaTalk.)
Actisense NGT-1 specs
Also, choose a NMEA GPS if you do not have or plan to buy a Raymarine MFD chart plotter.
