Hi, I posted this https://www.rcd330.com/question/echo-on-5gd035280b/#answer-13081 Connecting first though bluetooth and after that with AA, does not help with the echo. It is still there. Using Android 12 (on a Oneplus 6), same with the phone of my wife (same specs). Do you have any idea? Already paired it again (first deleted on phone and on radio), also does not help.
