Garmin protocol functions found in other devices. This includes the PVT
(position, velocity, and time) protocol. On the nuvi 350 and some
others it includes the waypoint creation protocol. This means that on
the nuvi 350 the GTRANS controller doesn't have to command the nuvi to
enter FMI mode, and that it's also capable (with the right electrical
interface) of talking to non-FMI Garmin devices.
If it detects that the connected device is capable of FMI 2.5 or later,
it has to put it in to FMI mode to use the newer waypoint creation
protocol, which is an FMI function and not one of the legacy protocols.
