Sometimes the functions of the car radio do not satisfy its owner, or a violation occurs in the work - the buttons do not react, the program is knocked down. In such cases, the firmware is required. You can try to independently make this operation.

Before proceeding with the firmware, you should look into the Internet and ask the developer's website, is there a new version for this model of the car radio. In most cases, the firmware is provided free of charge, so it is worth a wary of the new proposals to "buy a new program". Thanks to fraudulent actions of some sites, you can not only spend your money, but also pick up a computer virus.
