So my xi5 had the GPS replaced in the spring of 2018 I'm not sure if I have the old GPS or the newer version. It will follow a route mostly ok and I always cancel NAV before I reach the end of the route.My biggest gripe is the cruise control will ramp up to full power on its own...wondering if the dongle addresses that problem...And for what it's worth Motorguide sent out dongles about a year after the Xi5 were released it was for the cruise control problem same thing plug it in to the gateway and Mail the dongle back.
