2500 series with Civic logo. Its the (specific toward Civic 92-95) optional radio am/fm cassette player which has a compact disc controller function and accessory phone function. Cd unit not included but are pretty easy to find.  This radio unit is the 2nd radio option for 1992-1995 Hondas for a period correct installment. Will plug and play all Hondas/Acuras from 1986-1997. Color lights up white. Small broken pieces on the left bottom corner. (as pictured) hard to notice when installed. Radio does not come with the security code but can be obtained by contacting you local Honda dealer and giving them the serial # printed on the sticker on the radio. The serial # is worn off on the sticker but you might be able to make out all the numbers putting gate label at the right angle. Radio was plugged in and CODE appeared so it should work after you get the security code. Very cool functions on this radio like mute button on/off button and a large display screen This is a very very rare radio don’t miss out.
