Step 5: Tune your vehicle’s FM radio to an FM channel that’s not being used in your area
Use your vehicle radio’s Tune function (not the Scan function) to find an FM channel (between 88.1MHz and 107.9MHz) that is not broadcasting in your area. If you’re not sure which FM channels are not broadcasting in your home or travel cities, you can also go to http://sirius.com/fmchannel and search for a suggested FM channel based on your zip code.
•Once you have located an FM channel that is not broadcasting in your area, save it as a preset on your vehicle radio. This will become your SIRIUS preset.
