Why doesn't the car CD eject the disc when the eject button is pressed?

[DiBennett]

If the CD in the car doesn't eject, it may be due to a malfunction of the car CD player or the disc being stuck inside. Here is some relevant information about car CDs: 1. Definition: Car audio systems operate in a very complex environment, constantly subjected to electromagnetic interference from the car's ignition system and various electrical devices. Since all electrical devices in the car share a single battery, interference can also occur through power lines and other circuits. To mitigate this, car audio systems use anti-interference technologies such as choke coils installed between the power source and the audio system for filtering. 2. Purchasing Tips: There are hundreds of audio devices available on the market. Experts advise that for most car owners, it's not necessary to equip everything from amplifiers to subwoofers. The primary principle when choosing car audio is to make the most of what you have. To select a satisfactory product from the vast array of car audio options, consider factors such as price, brand, and the reputation of the dealer.
