This would be an excellent improvement.
One of the really big weaknesses in the otherwise very good BMW Connected navigation app, is that it shows all roundabouts as straight ahead, the rider entering at 6 o’clock, exiting at 12 o’clock. It then relies on an instruction “Leave at exit 4”, requiring the rider to count the exits. This is made harder as some very small exits (say only into a farmer’s gated field) are counted as an exit, which only a farmer would ever take.
Garmin, with their years of perfecting the display are much better.
