Now that the update 13.24 is live, does the software of the 945 LTE have major differences with the 955?
It's very decent. I don't use maps but I do geek out on the training readiness, stamina features which are 955 level and they work great. The only problem I have had is that some larger connect IQ apps crash, seems to be that it doesn't have the same memory.
I am facing a plethora of bugs with the SW 14.52 of 945 LTE (and all SW versions before), so I generally cannot recommend this watch.
Bugs related to various navigation failures in many respects (too many to name in detail), bad map panning performance (unlike FR 945 non-LTE), sporadic crashes during activity with navigation, or watch stopping tracking by itself without me stopping the tracking explicitly.
If you are happy with the 955, you have been warned.
