Hi, I was given a radio/cd player taken out of a Montero Sport to put on a 1997 Mitsubishi Mirage and fits perfectly and plugs in as if was from factory however when I turn it on is asking for a code. Is there any way you can get it for me? This is the serial # 02074107A and there is a MR# 490089 and also is DY-2U05W _____________ 34U0068, I would greatly appreciate if you can help me with it. Thank you, John
