Updating my own post for future searches... I called raymarine tech support and after a short hold was connected to a tech, to whom I explained the symptoms and the steps taken so far and he acknowledged that the issue with extreme compass deviation was most likely (pretty much certainly) software-related. The gentleman was well trained and familiar with the products. The fix requires the firmware to be updated in all of the related devices, and it requires one of Raymarines chartplotters to do so. He advised that the "classic" series chartplotter was not up to the job and strongly recommended a MFD running Lighthouse ii. Good news is that my local dealer has agreed to lend me a demo unit to do this update. So, its solvable but the entire thing remains disappointing. This is a lot of work to resolve a product quality issue, and it will need to be done periodically to keep current. I note that Raymarines site and documentation admonish that the firmware must be kept up to date, while also warning that firmware updates are done solely at the owner's risk. This, you apparently consent to by downloading the update, which as just mentioned they strongly encourage you to do, no doubt to fix the bugs they are aware of but keep on the down low....
Before investing in marine electronics it is well worth understanding any bugs that might be associated with the product and its software, and also on the process for updating firmware/software, since you will have to do it. End of the day, the raymarine autopilot and any other other ancillaries appear to have been engineered as and should probably be thought of as accessories to their MFD, rather than viable standalone products.
