How long is it now since the 820 BT connection issue was introduced? There was a comment from one of the Garmin mods that it was being investigated, but several firmware releases later there has been no sign of a fix.
I'm tempted to say that this is typically bad attitude from Garmin, not acknowledging that the problem exists, let alone doing something about it.
Garmin, how about giving us an update on this? Pretty please?
