I think you're on to something. The current HB units may not have the processors to handle "Livescope" input. As some on here have experienced, HB has introduced features that force you to upgrade units to use them. Maybe the plan is to introduce the units now and "Livescope" in the spring. The number of Livescope and head units Garmin has sold to take advantage of it must be staggering.
