Bob,

One of the limitations/features of marine electronics systems having components from more than one manufacturer is that the software within products of one manufacturer are not designed to be updated by products from another manufacturer. Accordingly, Evolution autopilot components are exclusively designed to be updated via a Raymarine MFD having a SeaTalkng communications interface. Should a system lack a compatible Raymarine MFD, then software updates to Evolution autopilot components may be performed by a Certified Raymarine Installer or by Raymarine’s Product Repair Center. If contacting a Certified Raymarine Installer to perform the update, be certain to inform the installer that your system does not include any compatible Raymarine MFDs.
