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

[Chuck - Raymarine - Moderator]

Korrigan,

As indicated within my initial response, ST70 autopilot control heads contain no end user serviceable part and the design of Raymarine products is considered to be proprietary. Our repair technicians have recommended that the software with the control head and autopilot course computer be brought up to the latest available versions:
- ST70 autopilot control head: v3.04
- SPX autopilot course computer: v3.05

Please click here to view a FAQ addressing options for updating software within these components within systems lacking a compatible MFD which is capable of updating the software within these components. Should the problem persist, then it would be recommended that the ST70 autopilot control head be sent to Raymarine’s Product Repair Center to be bench checked / serviced. As indicated within the referenced FAQ, the ST70 autopilot control head's software may be updated by Raymarine’s Product Repair Center.
