I would like to add the stock MFT to mine but I havent found 1) anywhere to pick up the unit 2) found any information on whether or not the swap is possible since the car didnt come with it. I know a lot of people hate it but I personally kind of like it. I have strolled upon the direct swap eBay units just as everybody else but they dont say anything about being compatible with Sirius, and thats something I am not willing to give up!
