Ok, So I bought a new radio and I need someone to lay out my wiring harness options. I drive an 06 Prix without a monsoon system, but it does have onstar (which I don't care about) and there are no steering wheel controls. I would really like to keep all the chimes and the date on my heads up display thing (which I know you can lose with some harnesses) and the RAP. What are my options? I know I can get a cheaper harness and lose these functions. Can someone give me links and recommendations? I tried crutchfield but they don't have anything that says it fits.
