I know my LT the my link stereo with touch screen. I don't think up grade would be hard. They don't change harnesses much. Cheaper and eases confusion on assembly line. I just wish my car had a manual or DVD or something to tell me what I have! It didn't even come with key fob! I had to call on star to find out that I had remote start! So for now I use my phone till fob comes in. I just hope they ordered the right one?
