The Lingdu driving recorder I just bought has an FM transmitter on it. The solution for how to play the sound of the recorder through the car audio is as follows:
The first one:
p>Does the Lingdu driving recorder have a headphone jack?
If there is a headphone jack, just buy a two-way 3.5 audio cable, then plug one end into the driving recorder and the other end into the audio cable in the car.
Second type:
If there is no audio line interface, you can directly find a mobile phone repairman to basically disassemble the driving recorder and connect the audio transmission line from the speaker on the driving recorder. Just retrofit a line to the speaker on the car and it'll be fine.
However, I suggest that you do not choose to change the sound to the car speaker, because this means that you will have to turn on the car monitor for a long time in the future. If the monitor is turned off, the speaker will also be disabled. If you are using the speaker, When listening to music, when the driving recorder wants to make a sound, the music will be paused, which will affect your mood.
