i bought a new stereo for my 2004 grand prix gt with the monsoon setup. i pulled the stock stereo out to find that the wiring harness i had purchased was different. so i went down to a car audio store to see what the deal was and they went on to tell me that there really is no harness because the display right above the stereo is run through the stereo. so in order to still have that i would need to wire in both stereos which sounds kind of like the go around your elbo to get to your ass way. is this true or is there something out there that will work so i dont have to do such ridiculous crap?
