Recently one of our customer gave us such a feedback about 2 din android head unit:When he made a call to his friend via Bluetooth,he could not hear the voice of his friend but his friend could hear from him clearly.

First,do not worry,I just would like to praise this customer,because when he encountered problem,he would contact us for help at the first time.I appreciate the solution way of this customer.Also,I really hope every customer,like this customer,does not return android car radio first instead of asking for help from our Joying company.

The following is solution to the problem Bluetooth call can not hear voice from the other people.

1.Please kindly open the function of Bluetooth audio and Bluetooth media on your mobile phone and also on the other people mobile phone.You could read this blog via https://www.carjoying.com/Joying-blog/20.html
