That's how I do it whenever I want a specific route. I map it in Google Maps, then use https://mapstogpx.com/ to make a GPX file, when I load into the GPS unit.Sure. If you create a route that specifically takes you on 50, the XT or Montana will honor that and run you the way you’d planned.
Mine can still occasionally get "confused" about where it's going and I'll have to reload the route to get it back. The 550 is fine with a route that I have made that doesn't have any roads that it recognizes (off road), but the 660 can't handle that correctly, which is why it doesn't get used on my bikes. Also, the 550 has a blue line where I've been so I can get back the way I came if I'm genuinely lost. The 660 doesn't do that.
Still, we should definitely chat in person.
