Eliminates outside static and interference sometimes experienced with a wireless FM connection.

Connect your Sirius radio directly to your car radio via the antenna jack. Compatible with all Sirius brand Plug & Play and personal radios. Includes the plugs and wires required for most installations. The direct connection eliminates the need to find an unused FM station and provides better performance. It directly connects the "FM Out" signal from the satellite radio receiver unit's internal FM modulator to your car head unit's FM antenna connection. An internal relay switches between Sirius operation when your receiver is powered "on" and AM/FM operation when your receiver is powered off, so you can still listen to your AM & FM stations.
