I use Garmin devices along with MRA a ZUMO XT and a 340 and 390. I've found that GPX 1.1 works better than 1.2 as you can see the shaping points as little blue dots on the Garmin devices. I tend to put a shaping point on every road I want to be on. If you are doing a circular route and download it as 1.2 and only P
put a start and finish waypoint in, then if you go off route the nav will bring you back to the end waypoint. If you have plenty of shaping points and use 1.1 the nav will bring you back to the route. I usually put a waypoint at the farthest point in a circular or out and back route so that the Nav always navigates to the farthest position on the route. I also tend to turn off auto recalculate and just navigate myself back to the purple line and/or make the track visible on the map so that I can see if the intended route is being deviated from.
