Replacing Car Handsfree HCA-20 with HCB-30
If you already have a Car Handsfree HCA-20, you do
not need to reinstall all the components for the
Bluetooth Car Handsfree HCB-30. You need to move a
few cables from the HCA-20 electronic box to the
HCB-30 electronic box.
To replace HCA-20 with HCB-30
1. Detach the bundle of power cables, ignition sense
cable, and (if installed) the music mute cable from
the HCA-20 box, socket E in the installation chart on
page 4, and connect it to the HCB-30 box, socket E.
See installation chart on page 4.
Note: Make sure that the blue ignition sense cable is
connected to the ignition of the car.
2. Detach the advanced music mute cable from the
HCA-20 box, socket D, and connect it to the HCB-30
box, socket D. Or, if you have an external loudspeaker
instead of an advanced music mute for your HCA-20,
detach the external loudspeaker cable from the socket
to the left of socket C on the HCA-20 box. Then
connect the HCB-30 external loudspeaker cable,
or advanced music mute cable to the HCB-30 box,
socket D.
3. Detach the microphone cable from the HCA-20 box,
socket C, and connect it to the HCB-30 box, socket C.
4. Connect the HCB-30 control panel cable to the
HCB-30 box, socket F.

Using the car handsfree
When the installation of the car handsfree has been
completed, we recommend that you test the
communication between the mobile phone and the car
handsfree by turning the car handsfree on, and then
pairing the car handsfree with your mobile phone.
See “To turn the car handsfree on” and “Pairing the car
handsfree” in the HCB-30 User’s Guide.
