If you have fitted a new battery then it is likely is that the radio has become corrupted when the terminals were removed from the battery. I would suggest a reset would solve your problem This would mean putting all the tuning etc back. In the user guide there is an explanation of how to reset on the first few pages. It is a small button on the front of the radio.

To reset the JVC KW-V21BT car stereo, you can try the following steps:

Turn off the car stereo by pressing and holding the power button or by turning off the ignition.

Locate the small reset button on the front panel of the stereo. It is usually a tiny hole labeled "RESET" or "RST."

Use a pointed object such as a paperclip or a pin and gently press and hold the reset button.

While holding the reset button, turn on the car stereo or press the power button to power it on.

Continue holding the reset button for a few seconds and then release it.

The stereo should reset, and the display may briefly turn off and then turn back on.

After the reset, the stereo should return to its factory default settings.

It's important to note that performing a reset will erase any custom settings or configurations you have made on the stereo, so it's a good idea to take note of your preferred settings before initiating the reset process. Additionally, consult the user manual of your specific JVC KW-V21BT model for any specific instructions or variations in the reset process.
