I have looked everywhere online and can't get any definitive information about installing an aftermarket Cd player into a 2001 prius. I don't want a factory one and I don't want an FM transmitter or a tape deck converter. I want an aftermarket CD player but I am a complete amateur and I have no idea how to do it. Best Buy told me they could not do it because there is not a harness kit made for my car... I am desperate for help.
