When swmbo uses her phone via bluetooth we can hear fine via the speakers.

However ,my son says he can hardly hear her.

She asked me where to direct her voice.i.e.rear view mirror,dashboard, steering wheel area?

I don't have the "comprehensive "yeti manuals to hand,so any advice gratefully received.

Small grille beside reading light above driver.

I've always installed my non OE handsfree systems too with the microphone by the rearview mirror. It is the best place as it does not pick up any road noise through the side glass. AND your passenger can join the conversation as well.
