My Garmin Edge 810 has freaked out on my last two 200s when following a self-plotted TCX RwGPS routes.
On the first, it crashed and reset at around 130km and although reloading the route worked, ride data to that point was lost and I had to dig out the .fit file to join with the recorded remainder. On the second, it seemed to lose the route completely at a similar distance, but again was fine after a save and restart.
This is hasn't happened before -- I usually split rides into inter-control stretches, but on these two, I plotted the whole route and instead marked controls with a custom cuesheet. The second bit worked, the first bit clearly didn't.
Anyway, I now gather the crashing/failing is all to do with the Edge's inability to work with more than a limited number of 'route things'. The question is, what are those things and what are the limits?
My cursory research has revealed a number of terms – track points, course points, route points, points -- and different sites/tools seem to use these terms interchangeably to mean different things.
On GPSies, for instance, I can reduce 'points' to 500 and still have 2600 'trackpoints' – so what's the difference and which is the important one for Garmin happiness?
Garmin, on the other hand, says "The Edge 510, 520, 800, 810, 820, 1000 and Edge Explore 820/1000 [have] a limit of 200 course points per individual course." But if course points are the point-to-point positions on a line that define the route that follows a road on a map, then that doesn't strike me as very many for even a 20-mile route...
Is there a solid primer on this stuff that explains the intricacies and terminology in a Gamin context..?
