If it's Honda Roadsync, the. It should use bluetooth. At least my wife's Rebell 1100T (same Africa Twin engine) does.Out of curiosity do you have to plug in your phone to use CarPlay or is it Bluetooth?
As an aside, although the 1100 inline twin does well on the highway, it can't compare to the ST's 1300cc V4, not that I've driven my wife's very much. The ST is buttery smooth in comparison and way more confortable, IMHO, for a road-trip. Which is why I limit our 2-bike rides to 4 hours daily or less.
All that being said, it's very capable on highways.
