Hello thank you for using JA let me see if I can help.
What will have to be done is to remove the radio and you will need to write down the serial number along with all the identification numbers found on top of the radio. The information will have to be taken to a mitsubishi dealership and the parts department will be able to provide the code. They are the only ones that will have this information. I would recommend talking to the service writer and he may be able to get this to you for free.
Well its indicated that I should not remove audio because it will not work. How about that?
Sir, you now appear more convincing. Its almost midnight and I'll try this tomorrow. Should I accept for payment now or after doing as per your instruction tomorrow?
