Can the Bluetooth headset be modified to the car audio system?

If your car audio has an AUX audio source input jack, this function can be achieved. The specific problem to be solved is the power supply of the Bluetooth headset and the signal connection between the Bluetooth headset audio output signal and the AUX interface of the car audio system. The AUX audio source input jack is an ordinary headphone jack, which receives small audio signals, which are then amplified by the car MP3 system and sounded from the speakers.

First of all, you need to prepare the audio cable with the headphone plug on both ends, cut off one end, and find out the corresponding head to connect to the output line of the Bluetooth headset, which is the Bluetooth headset speaker cable. Leave the headphone plug on the other end and insert it into the AUX jack. In this way, the audio signal of the Bluetooth headset can be transmitted to the AUX interface, and then the audio source can be selected as AUXIN on the car stereo to use the Bluetooth headset.

The easiest way to say this, the disadvantage is that you need to switch the audio source of the car audio to AUX IN when you call. There are more advanced modifications that use Bluetooth headset incoming call signals to trigger the relay and automatically switch the audio source to AUX IN when a call comes in. However, this modification is more complicated and requires knowledge of digital and analog circuits.
