I am sorry that you have not been helped yet. I just came online and saw your question.
It is possible that it is an antitheft issue. I need to know if you hardwired the stereo in or use the correct harness adapter for it.
Ok, let me see if I have the audio system wiring diagram. I need to know the options on your original - cd or cassette player, number of speakers
Well, I will have to opt out and see if another expert has the needed diagrams to find the issue. Sorry about that
