I just installed aftermarket cd/mp3 player in my ls. Let me tell you it is a major PITA!!!!!! This was the most difficult install out of any car i've owned. I got the proper wiring harness and dash kit but when all assembled the heater controls part sticks out further than it did stock and what our tech articles left out is that you still have to use the factory metal dash brackets that came from factory radio onto your new plastic in dash kit. if you do'nt then the heater controls won't be in dash securely and it will fly out! My car is 2000 ls v-8 without alpine system with 6 disc changer in glove box. This was a total nightmare although my stereo sounds 10xs better my dash looks stock but if you know what its supposed to look like you will notice the heater control flaw of it sticking out beyond the ash tray and heated seats buttons.
