The following changes have been made to NAC-1 Autopilot Computers:
- No AP Computer Alarms. A fix for “No AP Computer Alarms” -- as seen occasionally on large NMEA 2000® networks -- has been implemented.
- No Drift in Southern Hemisphere. Some vessels have not been able to use “No Drift” mode in the southern hemisphere. The issue has been located, fixed and verified.
- N2K Serial number. The N2K serial number will now match the sticker.
Not all installations will require this upgrade, please upgrade units if issues are experienced.
Software upgrade can be done from AP44/48 and IS42 using USB, MFD using the SD or microSD card slot, or by using the ST10 and swup tool software.
