I updated my TiVo Roamio Pro and it's connect TiVo Mini to the new Hydra interface. I decided to get a new VOX Remote for the mini since it's missing the Back button (I know you can use the Zoom button instead) and many of the keys are beginning to have their symbols wear off.

The remote arrived today and I installed the included bluetooth dongle in the Mini and attempted to fully pair the remote. The remote is able to control the Mini through IR mode, but it will not complete the final bluetooth pairing even after trying to do so manually through the menu. The yellow lite just blinks for a while, but never completes the final pairing (the light flashes red when issuing commands to the TiVo, a sign that it isn't completely paired).

Any thoughts on what I might be missing?
