The radio was improperly installed; there are two 12V leads, one services the radio when on, the other, only the circuitry for the clock and presets.
Eventually, this shouldn't be needed if the manufacturers ever think about using a little bit of flash memory for the presets and a coin cell for the clock.
You didn't give any model number so researching the manual is impossible.
If you can find the model number, look for a user's (or installation) guide on line to find the wiring info.

Hello headbanger42,
First I'd check all of the wiring and connections. Make sure that there's no bare wires, no cut or frayed insulation and no wires contacting metal on the vehicle or other wires.
If everything is connected properly and there's no shorts, press the reset button on the panel holder using a ball-point pen after detaching the control panel. (The clock setting and preset stations stored in memory will be .)
If that does not work, there's most likely an internal fault and the receiver needs service.
Hope this helps.

Hi, read instructions online for other JVC models as they have the same silly auto tuning function. Page 8 on this link. http://www.jvc.co.nz/assets/pdf-manual/KD-R406.pdf
