How to Switch Internal/External Microphone
Quiet, silent or echoing calls
- With the vehicle parked, compare a regular Bluetooth call with a CarPlay call using the same phone. Ask the other caller what they hear on each call.
- If only CarPlay is affected, record the phone and head-unit software versions and follow the CarPlay troubleshooting guide.
- If both calls are affected, check the microphone type and selection. For CC4 Pro, follow the digital microphone installation guide and external microphone selection guide. For other units, check the analogue microphone and adapter specified for your model. The video below applies to CC3 and CC3 2K units with newer boards.
Check your unit before changing microphone settings
This guide applies to supported newer-board CC3 and CC3 2K units. Check the board-identification guide before using its instructions. CC4 Pro digital microphone setup is a separate procedure.
If the switch is absent or the connected microphone is not identified, send the exact unit and microphone details privately to support. Do not physically remove the internal microphone as a general next step.
This is a guide which will show you how to switch from the onboard microphone to the external microphone.
This method only applies to the CC3 2K and non 2K units that have the newer boards.
