Product Description

Adding satellite radio? Direct connection to your radio eliminates the need to find an open or unused FM channel. The SiriusXM Wired FM Direct Adapter Kit provides a static-free audio connection for XM and SiriusXM dock and play portable radios hardwired directly into your vehicle's car stereo. Works with PowerConnect radios and vehicle kits.

Amazon.com

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.

Works with one caveat

Reviewed in the United States on January 8, 2016

*: Standard PackagingVerified Purchase

Bought a Sirius radio for Christmas gift and bought this to include so the install would end up a bit more professional. While it does serve it's primary purpose, it is not as good as the older version that Sirius used to have (and they have discontinued this model so I don't know what they offer now) The old model that I have in one of my vehicles plugged inline with the antenna like this one but does not cut out the regular FM signals when the Sirius radio is powered on. This let me switch to regular radio stations on the car radio without turning the Sirius radio off. This unit however disconnects the actual antenna signal when the Sirius radio is powered on so if you want to switch to a regular radio station, you have to power the Sirius radio off. That is the reason for taking a star away. Since even this version is discontinued, it is unclear what Sirius/XM is attempting to do with their marketing. They still sell the standalone radios but even now, several years after the merger, they have different radios for Sirius versus XM. The XM radio I bought was nice and has a lot of features but compared with the one I bought around 7-8 years ago (Sirius) what you get is a bit slim. The only connection method included is a straight pin audio accessory connector which is why I had to get this item. Not sure what S/XM expects you to do if you get a new sat radio and your existing car radio doesn't have an audio jack. If I had to do it again, I might search harder for an older style or alternate product that performs the function without the FM signal glitch.

Works Great....When it is working...

Reviewed in the United States on May 14, 2018

*: Standard PackagingVerified Purchase

I bought the first one and it was a little difficult to install because I had to remove the console and half of my dash to get to the antenna connection on my stereo system. After installation it worked great. Sound was dramatically better than using a cassette adapter or the crappy FM transmitter on the Onyx SiriusXM receiver. However, after just over 6 months I started losing the AM radio signal. (YES, the Sirius radio was OFF!). After about 5-10 minutes the AM signal would be back. This would happen about once per month. Quite annoying when you're listening to something interesting on the radio. Today, it got worse. When it happened the AM signal was restored about 20 minutes later. Then later in the afternoon it happened again! I did buy another one of these back in March. I suppose I will have to try the new one. I am not too thrilled about having to tear the inside of my car apart again.

Better sounding option than other manufacturers

Reviewed in the United States on January 13, 2019

*: Standard PackagingVerified Purchase

I bought a different FM adapter before this one, which required a power supply and caused engine noise in the audio. I was not impressed. Then I found this unit and it worked so much better than my other attempt. No power supply to connect and the audio quality is superb. No more engine noise and having the SiriusXM receiver routed directly through the radio provides the best audio quality I've experienced with my satellite radio. I highly recommend this adapter to anyone looking to do the same or similar setup for their vehicle's radio system.

Night and day difference in sound

Reviewed in the United States on January 31, 2016

*: Standard PackagingVerified Purchase

If you are using the standard FM over-the-air modulation feature of the XM tuner, this direct wire adapter will dramatically improve the sound. It's like going from flat sounding staticy radio quality to CD quality with much better spatial separation of bass and treble.

If you don't use this adapter, you can find vacant FM channels: search the web for the radio-locator website "Find Unused FM Frequencies in Your Area." This will reduce potential interference if you pick a channel that is not competing with a strong signal.

The old version of this adapter (Audiovox silver metal box) used to have a plug on the side for the XM antenna. The new version (Sirius plastic black box) simplifies the wiring so the XM antenna plug can go straight to the XM tuner, it doesn't have to daisychain through the adapter first.

The way this plugs in is super simple. The hardest part is figuring out how to route the wires so it looks nice in the car. In our car this was located behind the factory radio, and the adapter wire goes up through the air conditioning duct and pokes out through the vent, so the wire is hidden behind the XM tuner which is also attached to the vent.

Great little receiver for your car.

Reviewed in the United States on September 26, 2018

*: Standard PackagingVerified Purchase

I have been wanting to upgrade the stereo in my car since it does not have an aux input,a 2007 Pontiac Grand Prix, but decided not to mostly because of issues other people have had with aftermarket stereos. So I wanted to keep everything stock and uncluttered. So I chose the Sirius XM Onyx Plus since it has a color screen and easy to use. I also bought the FM modulator that connects to the inline car antenna wiring in order to hear the satellite radio, and it works and sounds amazingly well! Installation of the XM antenna was easy just mount it on your roof and tuck the wire under the weatherstripping and to your receiver. I don't like the vent mounts because they are crappy and block airflow, however I found a company that makes custom mounting brackets for most any car and you install it right along the side of the factory stereo. Its very sturdy and has the mounting holes for your satellite radio. Its called Panavise and they are a little pricey but well worth it.

A great add-in for any Sirius system

Reviewed in the United States on June 24, 2016

*: Standard PackagingVerified Purchase

Thiis is a must have if you don't have an AUX in on your car radio. A simple in-line tap that works very well across all frequencies. Most importantly, this has interrupt circuit so if you turn off your Sirius receiver, the FM connection to your radio is re-established for clean audio.

When using the Sirius, I found the "FM reception" to be superior to the broadcast FM transmitter of the unit - far superior.

It takes a bit to install as you have to remove the radio, but the time and energy is well worth the effort.

Crystal Clear FM!

Reviewed in the United States on January 10, 2020

*: Standard PackagingVerified Purchase

I didn't think that FM could possibly be crystal clear but this made my Sirius/XM sound the best I've heard it so far. I'm used to getting some sort of noise, even with the AUX plugged in, but this thing has no noise. This makes the channel completely silent when no audio is playing. Very satisfied with this purchase.
