I just installed and everything works, but the audio during a phone call isn't very good. The incoming audio has a high pitched noise (not alternator whine) whenever the other person talks. I've updated the firmware to 1.05 and my iPhone is at the latest version.

Anybody else having this problem?

Noticed today that the audio problem is only when connected via the USB and in Apple CarPlay mode. The audio is fine when connecting via Bluetooth.
