I recently bought a used infiniti, and the person I bought it from just put any old stereo that fit in the dash to fill the hole and make it look better. He told me it wasnt plugged in, so I checked and it didnt even have the right connections for the car, so I bought the right cords and stuff and hooked it up, but now it asks me for a code. Can someone please help me, or know how I can get the code? To my knowledge, it is a 2001-2002 Honda Accord OEM 6-disc CD Changer with Cassete player and Radio. Model No. 39100-S9A-A200 Ref.
