FFS!!..... After 2 hours of nearly going crazy and tearing my imaginary hair out (I'm bald) and now not bothering to go on my planned ride this afternoon!... as I've finally just discovered the 100 courses limit in my Garmin 830.
I tried syncing via phone, wifi, cable... absolutely nada, I then tried different routes, creating another route - just in case the file was corrupted, tried route planning on Garmin, Strava, RideGPS - nada!
I thought my device was broken.
Okay, Garmin has decided on some arbitrary limit... fine, but what would be really really helpful - if there was some notification either on the Garmin Connect app or on the device itself that the limit had been reached... thus saving me or potentially anyone else of 2 hours of absolute ballache!
