Depends on the year and the stock radio. Some radios are equipped with a jack for the Satellite module, others are not. Later ones must be programmed to accept the module or recognize the option. Look at the parts books, see what you have and search for the Satellite module on ebay or in a junk yard. They were usually deep under the console. You'll also need the harness if it's not in the car, the antenna and its wire.
