The USB version of Garmin GPS receivers (like Garmin 18) do not support NMEA, they only support
Garmin's own protocol. Therefore very few GPS applications can use Garmin USB GPS receivers.
GpsGate solves this problem! You can connect GpsGate to a Garmin USB GPS and GpsGate will make
the Garmin GPS appear as a normal NMEA
GPS connected to a serial port. And! You can connect any number of GPS applications to
the GPS at the same time! Including nRoute!
