Frequently Asked Questions - OV-CR-422 Overmax

Why is the unit not powering on?

Check that the car ignition is on and the voltage is stable (12V DC). Verify the fuse is not blown; replace with same type and current rating if needed.

No sound from the speakers.

Ensure the volume is turned up and not muted. Check speaker connections for short circuits. Adjust Bass, Treble, Balance, or Fader settings.

Radio reception is noisy or weak.

Confirm the antenna is firmly connected. Try adjusting the frequency manually or use automatic scanning. You may be too far from the station or in an area with interference.

Volume is very low even at maximum setting.

Check if the speakers are short-circuited. If the environment is too hot, let the unit cool down and try again. Also ensure the Loudness function is off if not needed.

USB or SD card not playing.

Re-insert the USB/SD card. Ensure the card is formatted correctly (FAT32) and contains supported audio files (MP3/WMA). Try a different card to rule out card issues.

Replace the battery in the remote. Ensure there are no obstructions between the remote and the receiver on the unit. Point the remote directly at the front panel.
