[Android Central Question]

This has frustrated me for years with both Galaxy S5 and Galaxy S8. No matter how I configure things (I've tried every imaginable combination of settings) it refuses to use the bluetooth mic to input navigation commands into Google Maps. It always uses the phone mic even when sending audio to the bluetooth device. This is especially frustrating with motorcycle helmet bluetooth, making voice navigation impossible when riding. Bluetooth mic works fine for phone calls, so the basic functionality is present. Has anyone else experienced this and perhaps found a solution?
