Actually I sometimes have this happen when just using my cellphone without being in my car.ECHO Occurs when using CarPlay to make or receive a call,
the other person (at opposite side) hears an echo of themselves on the line
I do not hear the echo at my end,
So I don’t always know when it occurs
This happens frequently (almost every call)
This issue has also happened with a Bluetooth connection to the same stereo...
I am using iPhone 7
It is not happening with my Fiat Linea, Honda Jazz (as I have 3 Cars)
I hear whatever I say repeated. Not sure what causes that but keep in mind there is a delay in actual voice transmission always. I think the echo is the delayed voice being picked up by the phone speaker and being re-sent.
