Still having teething issues with mine which I’ve highlighted in other posts.
A few things. Firstly, in following a downloaded TCX file the E820 was constantly ‘off course’ due to being more accurate. Or at least more accurate than the device the TCX file was recorded on.
This can also be said for general riding and Strava. Upon uploading a ride into Strava I’m noticing segments missing due to partial or no match.
Some of the elements have been user error e.g. leaving sampling on smart rather than 1 second which resulted in missing Strava segments again due to straight lining an aspect of route.
Also, I should have perhaps tested the maps and navigational features somewhere familiar before riding something new.
Apart from these niggles I’m liking the E820. The settings and functionality are endless.
