I don't know if anyone else here have this problem but for me even when a software is 100% phase, garmin express still can't find the update. It find only maps update. I am on 13.51 beta software. Thanks!
Well, wouldn't 14.10 be the first official software after 13.51? 13.40 is older than your 13.51 and 14.10 hasn't rolled out fully yet. So before it gets fully rolled out and you still don't get it, everything is working as it should be, AFAIK.
