Just bought this Wired Relay for my Sirius S50. With this adapter you don't need to have to use the FM modulator that comes with the stock car kit.

The installation was very easy and has preformed exceptionally well. I drove through Dallas and Houston on my last trip and never had to change channels.

I bought mine at Best Buy for $30 but you can find one online and save a bundle. Its well worth that small investment and makes it even safer while i drive since i dont have to change the channels every time i lose the signal.



Give it a try

 

I have one of those for my XM as well. Absolutely LOVE it.

 

Gotta agree the FM modulator, didnt cut it, lasted about a day after I got my Sirius. However, I didnt go "all out" and get a wired relay. I just borrowed my tape cassette adaptor from my portable CD player, plugged it into my Sirius. Works like a charm.

I would definitly recommend the wired relay, if your truck doesnt have a tape cassette.

 

I tried the cassette adapter and it worked great until ...

The motor in the radio burnt out. When they replaced the radio the new one was a cd player.
