i have an O4 LS and i want to put an aftermarket system in it. my only problem is i know that my factory stereo has all the vehicle settings like resetting my warning lights and my chimes and stuff. a buddy of mine told me that you can still run a system with the stock radio you just have to find the kit to do it... can someone verify that? and if its not true then is there anything that i can do, i dont want to put an aftermarket stereo face in it if i dont have to. so any help would be greatly appreciated!!
