Ive got a question. I have had my truck for about 4 months and the Sony radio it came with really sucks. Truck has radio controls on steering wheel. I want to go back with a factory radio but dont know if it originally had xm. I would like to have xm. How would i be able to tell?:help

Do you have the OnStar/XM antenna? Not sure on the VIN, more likely the code listed on the glovebox tag though.
