Installing the JL4001
External Microphone
The JL4001 comes with a built-in Bluetooth microphone,
but we also include a high quality external microphone.
This external microphone will work at just about any
location, but we do have some recommendations for
placement. Try to keep this microphone away from any
windows, air vents, or speakers to avoid background
sounds or feedback. The external mic will plug into the
back of the head unit via a 3.5mm headphone jack plug.
Cameras
Your JL4001 is designed to automatically display a
backup camera anytime your vehicle is in reverse,
