It is okay to start the car and listen to music without putting it in gear.

How to listen to music without starting the car: Just power on the car, that is, turn the key to the ACC position (with a push button to start), and you can use the electrical appliances in the car. Listening to music when the car is not started will seriously damage the battery and can easily cause battery loss. If you do not start listening to music for a long time, the battery will be easily scrapped. Extensive use of electricity will cause excessive discharge of the battery, affecting the number of times the battery can be used. At present, many cars have on-board battery protection functions, that is, if you do not start listening to music, the power will automatically cut off after a period of time, because you are afraid of battery loss.
