Google Navigation problem

[Kessie]

When I have navigation on, and I take a call, the directions still come through the loud speaker, not the earpiece, and it is too loud. Any fixes?

Seems like something Tasker should be able to do but I don't see a distinct navigation volume setting and I'm not sure if any of the other volume settings would do the trick.

I should hope not. It is dangerous to drive, navigate and conduct a phone conversation at the same time. And since it is dangerous to others, it is anti-social behavior.
Either stop/pause navigating and driving to take the call, or ignore the call.
