My brother-in-law bought a new 2019 Mazda CX5. The microphone is really lousy to the point that sometimes you can hardly hear him on a call.
I know very little about car electronics, but want to give him some guidance. Should he just talk to his dealer about replacing the existing mic with an aftermarket unit?
I don't know what I don't know on this topic, so would appreciate any input.
If it's not simple, it's not sufficiently advanced.
