Ford Sync radios come with features such as hands-free calling and traffic alerts. Some Sync radios also come with Sirius satellite radios. To activate the satellite radio, you’ll need to acquire the radio’s electronic serial number. Once you have the ESN, you can contact Sirius by telephone to activate the radio. You can view the ESN on Ford Sync radios by pushing a combination of buttons. The ESN then displays on the radio’s screen.
