Got my 965 a few days ago from REI. Setup went fine, all good. I tried to pair with the vision display and it actually paired right away, BUT.... as previously noted it shows a message about adding custom data fields. Unfortunately even though there are custom data fields for cycling, the screen is frozen. Had to do a hard reset to get it back. Tried again and same thing. Even though the product specs on the web site under "cycling features" specifically say it is compatible, it is not. Sadly I am not willing to give up the display functionality for the new features so back to REI it goes.
