Interesting question though, will be a while before it will be resolved. Makes you wonder why it was not part of the gen2 bikes. That is one thing that I really wish was part of the OEM package. GIPro is the way to go I guess.
Actually IBzx10R I am curios if it would work also but not for the Gear Indicator as I have a GiPro for the moment.
I like the looks of the dial face much better and it uses real glass versus plastic that is prone to melt if parked in the sunshine in the wrong direction. So I may be replacing mine in the future sometime as well.
