Hands free phone call – Receiver has an hears his own echo


I have an IPhone 7 and it has the latest update IOS 13.4.1. I have a Renault Captur from june 2019. The media Nav system is fully updated.

When I make phone call or receive a call the recipient says that they hear themselves in echo. In the car everything is ok and clear.

Since the recipients hear themselves in echo they do not want to speak to me.

I have contacted the car dealers workshop and they can’t find anything wrong. They inform that the Media Nav system is updated.

How do I get rid of this echo business?
