Pioneers CDX-FM1287 12-disc add-on CD changer will play your home-burned CD-Rs and CD-RWs, in addition to your standard CDs. The double-floating, anti-vibration system protects the changer from skipping, so you enjoy flawless playback. A wired display/controller and a wireless remote are included for easy operation. Pioneers add-on CD changer installs conveniently — thanks to its built-in FM modulator, theres one less box to mount. The changer can be mounted at any angle (from horizontal to vertical), and doesnt require any modifications to your car. Output level adjustment lets you set CD volume to match that of your radio, so theres no annoying jump in volume when you switch between the two.
