Optional Cellular phone din + Cassette radio am/fm unit. Colors for the radio light up white to match interior colors at night. Includes radio code and is functional (although it seems the volume knob cuts the sound in and out with static). Could be a easy small tighten of a nut. Not quite sure. Also cassette was not tested. Cell phone unit will plug and turn on to add color to your dash at night. Will not work with current cell phones and is more of a visual piece. Lights up green with amber #s. Rare factory option for your Integras.
