Yaris 67 plate query re. Mobile phone

[AlfK]

Hi everyone, 

Have owned my yaris 67 plate for 18 months and being a retired OAP haven't had much cause to answer my android 9 huawai phone when in my car (my previous 12 plate yaris had similar bluetooth handsfree via the multi-media unit - I think? Which always worked well with my mobile). 

My issue is that I received an important hospital appt. call whilst in my car and the caller kept saying they couldn't hear me. I could hear them loud and clear. 

My question is - does my yaris have a built in mic (if so where is it?), or does the onboard bluetooth use phone's own mic? My phone was in my pocket at time. 

I have checked the units volume settings and maxed out both incoming & outgoing call volumes.

Am on the latest multimedia April 2019 software. 

Thank you for any help/advice in this matter
