Amazon.com Product Description
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.

Customer Reviews

Pleasantly surprised!
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.

Sirius FMDA25 Wired FM Relay Adapter
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.

So much easier than switching stations
We travel out of state a lot and did not want to hunt for clear stations to receive my Sirius radio and this product works like advertised. Just tune into the one frequency and voila, clear stearo radio no matter where you are.
