My stock stereo quit working entirely in my 06 STS fuses have all been checked and are all good. I have an aftermarket stereo I’m wanting to install but I’d like to hardwire the head unit as I don’t really wanna purchase the $125 interface. But I’m having issues with getting it wired. Could anyone tell me the wiring color codes? Also when I did get it wired it would say key fob not detected or would shut the car off. Currently I have everything taken out and have been using the vehicle without a radio (which with as much driving as I do it’s killing me lol) can anyone help me out please ?
