Firmware
What is Firmware?
The software inside the device itself. It determines features, menus and supported messages, and on many devices it can be updated.
What matters about Firmware in practice?
Whether a chartplotter shows certain on-board data often depends not on the electrical system but on the plotter's software version. Check this before buying, not afterwards.
Before an update, read the release notes: what is new, what was fixed, which hardware versions are affected. And never install an update while under way, only when the system is not needed.
