Tired of relying on your FM transmitter to send your Sirius satellite radio signal to your car stereo? Turn instead to this wired FM adapter, which provides a direct connection to produce a crisper overall sound. Unlike FM transmitters--which often suffer from static and interference, as with traditional FM stations--the FM adapter plugs directly into the rear of your factory or after-market stereo, thus requiring a bit of installation expertise. But once connected, you can tune to your favorite Sirius channels in seconds without searching for unused FM frequencies. More importantly, the signal will be clean and uninterrupted, with no pops or fizzes as you drive from one part of the city to another. The FM adapter, which works with all Sirius plug 'n' play and personal radios, includes plugs and wires for most installations, although antenna adapters may be required for select car stereos. It's also backed by a one-year warranty.

Easy to install and it works great!

It clears up all static and sounds like you are listening to a regular FM station.

Also, did not need adapters, antenna plugs were fine...

I must say I was pleasantly surprised by how well this product works.

I have an 07 Accord so it was a bit of a PITA figuring out how to get to the radio antenna in the dash. If you google around for your car and "remove radio" you will undoubtedly find directions for accessing it. That was the most difficult part and it only took me about 30 minutes from start to finish.

I recently got the Starmate 4 for my car. I had one of the old original Audiovox units from when Sirius was first starting up. It was huge, bulky, I had lost the mount for it, and it got VERY hot when in operation. Almost so hot that you couldn't touch it. Hence I decided to upgrade to a newer model. When I received and installed the Starmate I was surprised to see that the built-in FM modulator was horrible. And when I connected the FM antenna extender it came with, it made the sound WORSE. The static made it almost unlistenable through my radio. I googled around and found that the FCC had stepped in and regulated the amount of power the FM modulators were allowed to emit. So my Audiovox unit was better in that fashion since it was built before the FCC rules were established.

To fix the problem I got this Wired Relay Adapter. Basically you plug your car's antenna into it, then plug the wire into your radio. The other end routes through your dash and goes into your Sirius radio. The reception is 100% clear now. No more static. The downside is that you have to a) remember to turn off the Sirius radio if you want to listen to FM because it kills all of the stations, and b) regardless of whether it is on or off it kills AM reception. I don't often listen to AM and guess I don't have a need now (except for local TV stations).

All in all I am VERY happy with this product. It took a Starmate that sounded worse than an old Audiovox I had, and made it MUCH better in the end. 100% worth the $19.99 for this item if you have the know-how to get into your dash.

Great product. I had major troubles with radio station interference when using the Sirius radio without this product. Once installed it disconnects the external antenna and eliminates the interference problems. When your Sirius radio is turned off, your external antenna works normally.

I highly recommend this product if you can't use a direct connection from your Sirius radio to your car radio.

I bought this because I have my Siruis hooked up to my motorcycle and I do a LOT of riding.
I am the type of rider who takes off not knowing where I am going, only when I need to be home, I am constantly in search of that road I have never been down so I never know where I will end up, and it was a real pain trying to find clear stations that would last for a few hundred miles,let alone the whole day.
I thought I would give this a try and installed it before a run to DC and I was very disappointed it did not work.
I have been working with, and hooking up electronics for over 40 years, so I checked and rechecked ever thing I could think of, and the only thing I could not check was the plug in the cradle that the receiver was in so I put the bike back together and saved it for another time, when I had more time and a different cradle.
Well that time came about a month later.
I hooked up the new cradle, all the wires turned the FM transmitter off in the receiver and NOTHING..no music just static and a big sad face,checked all my connections again and they were good, but I still had nothing.. I just didn't get it, from what I understood, once this was hooked up it would broadcast the music on all channels, why wasn't it working??? so disappointed started to take it apart again, then a little light bulb clicked that said "try this", so I went to the known station in my area that has full power and a good clean signal 93.7, I went back into the menu on the Siruis receiver and turned the FM transmitter ON again and set the transmitter station to 93.7.
With the radio playing some forgotten song( it was actually playing golden earing's radar love)
I powered up the Sirius unit and Viola!! music!! right from the receiver and no more golden earing.

The product has good build quality and the installation is very simple. I bought this product without doing full research. My main intention was to use this as an AUX input for my factory stereo. Sad to say it doesn't work with any mp3 player or iPod or phone. The technology that's being used has to do with RF signals. If you are looking to hook up an mp3 player through the rear radio input, what you really need is a FM modulator. A FM modulator will convert the RF signal into a digital signal. I'm giving the product 4 stars for build quality and ease of installation. Though I feel the manufacture should inform the potential buyers that this product is not directly compatible with any mp3 players...

I examined many of these adapters trying to determine what would work best for my XM radio receiver. Most looked about the same and the price varied greatly. Althought this one was less expensive than most, it seemed that it would do what I needed. I installed it in my Acura RSX and have been extremely pleased with its performance. Spots where the signal would previously drop-out are now strong and I don't get any interference from the FM stations, at all. The only downside in that I now have to turn off my XM receiver if I want to listen to standard radio stations, but I think that is to be expected with any of these because when they detect a signal from the XM receiver, they disconnect the car's radio from the car's antenna. This is why I don't get interference from the FM stations anymore. I'm very pleased with this device.
