Upper Limit for Turn-by-Turn on Garmin Edge 500 for Brevets
Hoping to complete my first 200k this coming weekend. I have been poking around (extensively) on the use of .tcx files for getting turn-by-turn directions on the Garmin Edge 500, but specifically for longer distances, as a first line of defense/to supplement the cue sheet. I remember reading somewhere that once your self-created route gets to century-length or longer, the Garmin can't hack all of the waypoints for each individual turn and can become prone to crashing or freezing. In all of the threads and forums I have searched, I think I found 2-3 posts that vaguely give an upper-limit course length based on personal experience. Some people say 100k+ gets iffy, other people have said 200ish-k worked for them, so I don't know what to think. It also seems to differ whether you use a .gpx to get the course map, or use a .tcx to get the map + turn by turn cue sheet. I really want to be able to use a .tcx for the turn-by-turn.
In my searching, others have said that splitting up the route into segments between each controle, and then switching to a new course, is one way to get around it, but it just seems like an additional thing to remember to do (that I might forget to do).
Could anyone either point me in the right direction (literally and figuratively) of this information in other forums, or offer their own experience/insight?
