Loading MRA Routes Garmin Zumo XT

[epv]

Thank you guys very much for the detailed explanations. This helps a lot.

I'm also mostly concerned about routes with maybe 5 - 8 shaping points, mainly just to keep to a particular backroad rather than a freeway, or select between two roads that end up more or less the same place, so that when I reach a fork it will at least jog my memory about which one to take.

With basecamp for the most part if I let the XT recalculate based on those points it comes up with the same path as basecamp did (and I assume this would be the case for MRA too if I use the paid-level map), so I guess it would be nice to not worry about accidentally allowing a recalculation, and I'd like the security of knowing that if i do pick the other fork in the road it will eventually come up with a reasonable solution to get me to the destination rather than back to the fork.

There's the rub. If you chose the other fork, and then let the XT calculate, the result may be reasonable, but it may also be completely unreasonable, especially if there is a freeway nearby. The most aggravating thing for me about this is that it recalculates the entire remainder of the route rather than just to the next route point.

Ahhh, ok. Now I get it. That is aggravating. I suppose at that point one could stop navigation and restart, selecting a more reasonable entry point. Still shouldn't have to, though.

Is this behavior a deviation from the way other Garmin units work? I have both a Zumo XT and a Montana 700i at my disposal at the moment so I suppose I could test it.

You need to have enough shaping/waypoints in your route to force it to go the way you want regardless of if you go off route and it has to recalculate.

Another good tip is to show the track too so you can see if it's different
