What are the reasons for a car CD player not reading discs?

[DiBriella]

There are several main reasons why a car CD player may not read discs: 1. Incorrect disc selection: Different CD players support different disc formats. Choosing the wrong disc may result in the CD player failing to read it. 2. Severe disc scratches: If discs are not properly protected in daily use, severe scratches or damage may occur. The optical sensor cannot correctly read digital information, leading to disc jams, failure to read, or even system crashes. 3. Dirty optical lens: The optical sensor is a crucial precision component. Excessive dust can refract light waves or even block their transmission, preventing information reading and causing disc reading failures.
