Although you see it all on the screen, do you actually use the car's OEM mic or does it use the phone's speakerphone?Yes, that is correct. When I look at the OEM Bluetooth connection on my phone, I have phone, contacts and messages enabled (audio is disabled). When a call comes in, I see it on my car HUD, and AA shows the person calling and I get the answer/hangup button.
One thing to note is I think as delivered, this didn't work like that on my HU. It might have fixed itself after doing a factory reset of the HU.
Do you have Sink Audio on or off in HUR settings?
Are you connecting wirelessly or via USB?
Thanks in advance
