I just received my V2 to replace my battery dead 3 years old VA3.
I did tried the older VA3 charging docks (I have two of them mounted on a charging stand, average looking from amazon) and without an bigger effort it won't snap-in. I did not wanted to force the connectors and for a very first time I have just charged the new watch with a supplied cable. But tinkering garmin could just charge me a 10% more for a package deal on cosmetically pleasing charging stand, instead of having a cable sticking out from the back,,,just my 2c.
