My wife and I are touring through Austria and Italy. I prepared routes using RWGPS, and loaded the GPX files to both my 1050 and my wife's 1030+. On the 1030+, the courses work exactly as they should - pick the saved course, wait for it to finish calculating, ride, and she gets a single purple course line on screen with prompts at each turn that automatically swap the display to the map screen for the turn.
The exact same courses on the 1050 are a real hit and miss affair. A couple have loaded and worked correctly. Most load and show a real dogs breakfast of pink and purple lines with arrows all over the place, such that it's difficult to pick what the intended route is, and I get no audible prompts for turns, nor does the display automatically switch to the map screen when approaching a turn, so I have to keep the display on the map to see where to go.
The 1050 appears to know the route being followed, as when I go off route, I get the prompts to pause navigation or recalculate - if I choose recalculate, this *always* fails, but when I get back on course I see "course found", but still get no navigation prompts.
I've taken screenshots of all these problems, but because we're only travelling with phones and Garmins, and the 1050 uses MTP, I can't get to the screenshots on it via USB to put them here.
