I have the Varia Seat Rail Mount Kit and it will not accept either a Varia RTL510 or an Edge 1030+. I know the Edge is not supposed to mount onto the saddle, however, I wanted to confirm that I wasn't mistaken that the Seat Rail Mount Kit will not work. I have the Garmin Charge Power Pack and understand how the locking mechanism works. Unfortunately, the Seat Rail Mount Kit is too small to accept either of my devices.
How is the Varia supposed to mount if the mount is too small?
Cheers!!
