As follows:

1. The car is set to play randomly. Adjusting it to play in order can solve the problem.

2. When the car reads the songs in the USB flash drive, the sorting is inconsistent with the daily sorting. Try the following two methods:

1. Rename the songs in the USB flash drive. Add numbers but no punctuation before the name of each song. For example, the original name "Little Apple" is changed to "1 Little Apple", and the next song is changed to "2XX";

2. Rename the same name. Add a letter before each song title but no punctuation. For example, the original name "Little Apple" is changed to "A Little Apple", and the next song is changed to "BXX". If there are too many songs, AA, AB can be used, and so on.

Attention

For the car CD audio system, the most important thing to pay attention to is dust prevention. The laser head is the most expensive and most vulnerable part of the CD. Although dust protection has been considered during the design process of the car audio system, special attention needs to be paid to dust protection due to road conditions.

Careful maintenance of the audio can effectively extend the service life of the laser head, and can also ensure the long-term high-quality music playback of the car audio system.
