[CA] [CA11] ST70 Head control not keeping basic parameters

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Korrigan,

ST70 autopilot control heads contain no end user serviceable part and the design of Raymarine products is considered to be proprietary. This is typically a symptom of very old software within the autopilot control head. The currently installed version of software may be determined via the ST70 autopilot control head's Diagnostics menu. It is recommended that currently installed version of software within the ST70 autopilot control head and course computer both be determined, and if found to not be the latest, that the software within these products be updated with the latest available Raymarine product software updates. Should your system not feature a MFD which is capable of updating the software within these products, then please click here to view a FAQ addressing alternative means of updating the software within these products.
