[CA] [CA11] St4000+ tracking Garmin MFD

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum JDGALE0070,

While having a correctly aligned autopilot compass is not necessary for an autopilot to operate in Auto (point and shoot) mode, it is necessary for the autopilot compass to be correctly aligned to properly support operation in Track mode. When the vessel is operated in the absence of current at the cardinal headings at a constant heading, do the system's heading and COG value match? If not, how much do they differ by? Additionally, there were several versions of software released for the ST4000+, some of which specifically addressed performance when operating in track mode. Which version of software is installed within your ST4000+?
