The fix for these issues actually is 74.00.230. I know some of the members on here are a little skeptical of updating their software but if it’s done correctly and the system hasn’t been previously corrupted there really shouldn’t be any issues.Are you using Android Auto or Apple Carplay when that happens?
A few months ago there was a bug with Waze and Apple Carplay. When you weren't using Waze, it would mute the driver side front speaker as if it was sending navigation prompts, but it wasn't.
The workaround was to input a navigation destination in Waze, then cancel it.
So I would drive the car without using your phone at all to eliminate a problem with an app. No Bluetooth, no Apple Carplay or Android Auto. And no Mazda Navigation, of course.
