The upper half of the coupling split during installation of the small retaining bolt. I was careful and used a light hand with the provided hex wrench, yet the coupling split. BTD advised me to contact Garmin directly about what to do next and I will update this review at the conclusion of my efforts.
I broke one pod of the old version that I was using. Bought to replace the broken and also upgrade at the same time. I'd buy it even if I didn't break my old pods, and install them and use the old pods for a backup.
