How to Install the CK121
The CK121 allows you to play music through your car stereo via Bluetooth even if your car does not have a built in Bluetooth function. You can also use the CK121 with other speakers that do not support Bluetooth and have an AUX port.
Setting Up:
Using the metallic dongle, plug one end into the port on the side of the CK121 and the other end into the AUX port of your car stereo or speaker.
Alternatively, you can also use the AUX cable.
Now you can pair the CK121 with your devices and start streaming music!
