What would be cool if there was a very simple low power display bluetooth which just displayed an left/right/upp arrow with a number counting down when to turn or stop.
Phones don't really work mounted on a bike, but a simple display could do the job. Sort of how android watch displays an arrow, but using a low power screen.
