SIRIUS radio. 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.
2.Turn on your SIRIUS radio. Press and hold the 
Menu button to access the FM channel number list on your SIRIUS radio. Tune to the channel that matches the SIRIUS preset on your vehicle radio. Refer to the Menu Options/FM Frequency section of this manual for more detailed instructions on how to do this.
Note: The FM transmitter in your SIRIUS radio is automatically set to FM channel 88.1. This may not be the best channel in your area.
Tip: If you regularly travel between cities with different active FM channels, you may need to find channels that are not broadcasting in each city. Several SIRIUS radio models can store multiple FM transmit channels, so you can easily switch to the best FM channel for each city.
You will also want to set the FM channels that are not broadcasting in each city as presets on your vehicle radio.
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.
Direct Connections
Direct connection provides better audio performance than a wireless connection and removes the possibility of interference from local FM broadcasters.
Direct Wired Audio Connection
If your vehicle radio offers an “AUX IN” or “LINE IN” connection, it is the best audio connec- tion available. If the “AUX IN” or “LINE IN” connector is located on the front of your vehicle radio, this is also the easiest connection. (Figure 11)
1.Purchase an audio cable that matches the connection type of your vehicle radio and your SIRIUS radio at your local electronics retailer. Your SIRIUS radio requires a 1/8” stereo male connector. Your local electronics retailer can help you determine the proper con- nection for your car radio.
2.Plug one end of the cable into the AUDIO jack on your SIRIUS radio. (Refer to Figure 21 on page 23 for the location of this connector.) Plug the other end into your “AUX IN” or “LINE IN” jack on your vehicle radio.
