2000 series optional Honda radio. 2nd highest radio option for 1988-1991 Hondas for a period correct installment. Will plug and play all Hondas/Acuras from 1986-1997. Color is green and not all the lights light up when illuminated. Please refer to the picture when radio was plugged in which shows how many lights come on. Radio has rear plug for cd changer and or equalizer. Radio has been plugged in and appears to have an issue with the Volume knob and has a buzzing sound. All the rest of the features like preset and radio station change buttons work. Screen works as well. This could be a very easy fix. This radio needs restoration but is worth it where these are impossible to find now. Missing the bass treble small knob and the large volume knob is loose and sometimes falls off. Still very very rare and can be restored to function perfect. No radio anti theft code required for this unit.
