All of what Kwaka has said...
Plus ..
Easier to operate .. Buttons and finger friendly
Status Leds tell you whats happening better the the Gen2
I use both.. still..
Gen3 on the bike... Gen2 in the pocket Just in-case... If you off and your bike goes one way and you the other way you have a backup in your pocket.
And that's not including the Phone but we know that coverage when you need it can't be relied on.
Hope this helps.
