Now add the ability to play your CDs in your classic car with your replacement radio from Custom Autosound. This Single Disc CD Player is compatible with your USA-630 or Slidebar radio and can be controlled with the buttons on your radio. Placement of the radio is small enough to hide under the seat or in the glove box, and can be mounted remotely, away from the dash of your vehicle. No need to worry about the player skipping your songs, Electronic Shock Protection (ESP) technology has been integrated into this player.
