it wouldn’t be in the player manual, it would be in the fm modulator manual, there should be a switch that you switch to have it play on a specific station. Remember though if the FM modulator is on your other radio stations will barely come in. All the box does is take the feed from your phono out on the Sirius unit and feeds it to the antenna feed into the radio.
ok well no manual came with this unit i bought. i do have the option to turn off the fm transmitter on the S50. there is also no switch or anything on the box
im sure the kit will do the job just fine…you just have to figure out how it works. if your getting a radio signal then the kit works. i dunno if you have to set the radio to a specific radio frequency or if the radio signal is supposed to be overridden when your satellite receiver sends a signal. try plugging in headphones to your satellite receiver to see if your even getting an audio signal.
