FM Adapter Better Sound for your Sirius

Written By Gatorman, Texas on Thursday, June 11, 2015

Crutchfield Customer Review (What's this?)

This makes your Sirius sound so much clearer - also no interfearance as just doing FM Modulation

Pros: Clear reception / better sound

Cons: More wires / additional cost

FM modulator is a smart buy

Written By Valdizzle, California on Thursday, January 22, 2015

Crutchfield Customer Review (What's this?)

Filters out static and weak radio signals very well. If your car doesn't have the auxiliary adapter this is a great alternative to avoid annoying interference from coming into your radio. I tried using the cassette adapter for my car but that started to not work right after a while.

Pros: Easy installation and easy to use.

Cons: Taking the time to take the bezel and radio apart to install, professional installation is the easy route but another expense. If you like to do car work this is an easy installation.

Works awesome!!! Use to have a lot of static with my Sirius plug and play in the car. Now, nothing. This unit wiped out all the static. Was super easy to install. Had it done in 10 minutes.

Pros: Wipes out all static, easy to install, good price.

Cons: Have to power off radio to listen to FM stations.

Product was extremely easy to install, and improved the XM feed by 100%. Only downside is that to listen to FM, you have to turn off the XM receiver.

Pros: Easy to install, works beautifully.

Cons: Must turn off XM receiver to listen to FM.

Another great product from Crutchfield!

Written By J Fran, Indiana on Saturday, September 14, 2013

Crutchfield Customer Review (What's this?)

FM Direct Adapter works perfectly as described in the Product Description. The audio is perfect, no hash or interruptions in reception.

Pros: Great price and was easy to install in my Dodge Ram Pickup.Didn't have to remove dash trim, just removed (popped out) courtesy light in cup holder, used long and narrow needle nose pliers to remove antenna from back of radio and then inserted adapter jack (antenna plug adapter) into back of radio. Inserted excess wire and adapter box through hole for courtesy light and snapped light back in place.

works ok

Written By Marc, Charlottesville VA on Saturday, April 20, 2013

This works OK except that I have to turn off my Sirius to get it to work.

Pros: Works

Cons: I decided not to use it and just plugged my Sirius directly into an input jack. If you have this available this is a much superior solution.

Bought this product before and it worked. Newly designed and smaller makes it sound like its a direct connection. There is no static and you don't have to search for a clear station. A+++

Pros: Price,easy to install

Cons: Wish that it had a input to use for other electronics. Other then that there are none.

FM direct adapter

Written By outcast, Colorado on Friday, June 01, 2012

Crutchfield Customer Review (What's this?)

Least expensive way to get good sound quality for Sirius Radio. On my 2004 Monte Carlo the install was a breeze, Took 4 minutes at most. Reached up under dash, felt for antenna cable and unplugged it. Then inserted the adapter cable the rest was hooked up. Tucked the extra cables and the box under the console. You do not have to remove the radio! On my 2003 Trail Bazer, you do have to remove the radio. This is done by removing the dash trim panel. The instructions from Crutchfield are fairly good. Also keep track of what screws came from where they came from, there are several different lengths. Take your time and watch for wires you have to unplug to give yourself room to slide the radio out far enough to get to the antenna. If you take the time to fill in your cars info, Crutchfield will send the instuctions and adapter cables you need. Very happy with the system and with Crutchfield.

Pros: Improves sound quality over the FM broadcast system, no need for the FM extender antenna.

Cons: If you have to remove the radio to install, takes longer.

Works okay but....

Written By JL, Connecticut on Tuesday, November 29, 2011

Crutchfield Customer Review (What's this?)

I knew this was what I needed, but going into it I had no idea what was involved. Having taken the time to read as much as I could online, I felt comfortable enough to attempt it rather than pay an installer $250 to put it in for me. The Crutchfield support however was not what I had hoped for. They tout they have all the specs you need and will send you the specific install instructions, yet neither the salesperson I spoke with online, nor the instructions I received, provided any clue how the components were to be hooked up for my vehicle. I spent hours figuring out what went where and installing it, only to discover they did not supply me with an antenna cable that I needed, which pushed my install back to the following weekend. I thought Crutchfield would provide with some type of wiring plan of what part goes where, but not only did that not happen, but then they did not even provide me the parts I needed. The aggravation involved was significant. A simple chart showing how to hook up, for my car, the parts they sent me would have gone a long way, but that was not provded.

Pros: Provided a way to get a decent connection from my FM radio to my Sirius Sportster.

Cons: Install was a pain (see above), and noise feedback. For some reason, if you have your FM radio on a station other than the frequency it uses for your Sirius radio, you get a lot of static. This means to use your FM radio as you normally would, you must first turn off your Sirius radio. It would have been nice to go from a Sirius station directly to another FM station directly, without having to power my Sirius Sportster radio off first everytime.

This was definitley worth the money! I used this on my girlfriend's factory radio because she didn't want me to "Mess with her car", so a whole radio swap was out of the question. It hooks up to the factory radio antena jack on factory radio's and give you a direct fm connection which is pretty good, way better than wireless fm transmitter. Worth the extra time to hook up.

Crutchfield Customer Review (What's this?)

When installing an "add-on" type satellite receiver in you auto, this is the only way to go
for a proper connection. This part should replace the other modulation connection parts
and pieces and be included with the receiver kit.
My only complaint is: the part should have a 90 degree male connector that plugs into
the radio. In my F150, I was unable to push the radio back into the dash due to the plug
sticking straight out and hitting the defroster duct behind the radio. I had to modify the
stress reliever on the plug to get it to bend enough - this should not have been

Crutchfield Customer Review (What's this?)

If you have a Siruis radio and are using a wireless connection to your FM radio this
product is a MUST. It works GREAT! No more fuzzy connections or constantly switching
stations to get better reception. Plus the folks at Crutchfield were a great help. When
ordering I came to a point where it said I also needed adapters. It was showing 3. So I
didn't know if needed just to pick 1 or all. I called the Crutchfield team and they helped
me out. It turned out I needed 2 of the 3 adapters. Installing it in my Cavalier was fairly
easy. It just took some time. To get to my radio I needed to take the dashboard off. But
Crutchfield supplied specific instructions for my car, with pictures, how to remove the
dashboard. Everything went smoothly and its installed and as I said works GREAT.
Many Thanks to the Crutchfield Team for outstanding service & support!!!

Written By Andy, Massachusetts on Friday, September 17, 2010

Crutchfield Customer Review (What's this?)

This is an awesome addition to your XM|Sirius radio. If you are using the built in transmitter
to broadcast to your car radio, you should get this. If your in your local area and have your in
car radio set to the same channel as your XM|Sirius radio, it may work well. When you start
to travel and FM stations change, you then have to alter the settings on both radios. This
device eliminates the need to change stations and keeps the XM|Sirius radio strong with no
static from your car antenna trying to compete with the FM transmitter in the XM|Sirius radio.

I purchased this prior to a trip to Florida. The order arrived very fast as usual and I installed it in about 30 minutes with help from the Crutchfield guide. Once everything was connected I turned on the radio and Wow! I could not believe the clarity of the sound.
Needless to say I drove from Buffalo NY to Port Canaveral Florida and back and never once experienced any static or had to change the radio station.
Excellent product! * Make sure your receiver is compatible*.

Spoke with tech support at Sirius two times and they said that with a 2.5mm (female) to 3.5mm (male) adapter that this item would work with any audio player. Should have tried to speak to a Crutchfield rep. to verify. This product did not work for my XM unit or IPod. I guess it does only work for the stated Sirius satellite players.

If you can hook up a VCR (or should I say BD player these days?), you can install this adapter. Easy, straight forward. The only way to get better sound quality would be an AUX input. But compared to wireless FM, it's TONS better. Recommended.

Best thing since Sirius itself

Written By justine79, Indianapolis, IN on Thursday, October 15, 2009

Crutchfield Customer Review (What's this?)

I have had Sirius for about 4 years now and I have always loved it. But when cruising through the city or riding on the highway alongside a trucker I was always getting more white noise than radio. It was very frustrating. Not to mention when on the road for travel and going in and out of FM frequencies. Sometimes it was more of a pain to listen than anything.

This is the bomb. Sounds like when I am listening to my unit at home! Easy as 1-2-3 to install! If you have Sirius and are using wireless transmitter you are not getting what you should from Sirius. Spend the money and install this on your own. You'll wonder how you ever listened to that horrible transmitter that is built in

This unit is extremely similar to the XM FM Modulator which works fantastic! The detail description here describes it to work on either XM or Sirius and it is made for Sirius only.

Crutchfield had no problem exchanging it for the correct one for my XM radio and that's why I keep coming back!

[Editor's Note: This adapter is for Dock and Play sarellite radios only. We apologize for the inconvenience, and we are glad we were able to take care of this for you. ]

I thought my Sirius Starmate was a broke unit until this.

Written By navreich, Olympia Washington on Wednesday, February 18, 2009

Crutchfield Customer Review (What's this?)

I have two Sirius radios. The first I bought several years ago and it has always performed exceptionally so I purchased a new one for my wifes car. I installed the Sirius Starmate Radio in her pathfinder and there was so much static that I thought it was bad unit. So I swapped her radio with mine and the Starmate still had the same horrible static in my Jeep.

I purchased this FM adapter, installed it, and now everything is crystal clear with ZERO static. The other nice thing is that you dont have to change radio stations because you will never have outside interference ever again! I keep my radio set to my favorite local station and my Sirius Starmate also set to that station. When there is power on my Sirius I get Sirius feed, when I turn it off the FM Adapter goes back to my outside antennae and I get my favorite local radio station.

I LOVE THIS! If you own a Sirius Starmate radio then you have to purchase this FM adapter or your radio is worthless.

I bought a Sirius Starmate 5 reciever a few weeks ago and it was basically useless until I added this product. Wow, what a difference. It is clear as can be now. The installation took only a few minutes and I was blown away with the instructions I received from Crutchfield. They were the absolute best I have ever seen from anywhere. I was also impressed with Lee when I spoke with him on the phone to place the order. I received the part two days after I placed the order. I definately recommend this product and Crutchfield. They will be my first stop the next time I order electronics through the internet.

Great itema dn very easy to install, the only issue I had was that I had to have a antenna adapter for my 2008 Ford Explore, which Crutchfield helped me get because without them I had no idea I needed it, and when I used the adapters, the one that comes from my radio and plugged into the direct connect adapter it was a looser fit than I would have wanted. I used some electrical tape to secure so it would not fall out. Other than that it works and sounds great and I do not have to switch channels as I drive. Once again Crutchfield's support and instructions worked perfect.

Finally Great Reception!

Written By John, Cranston, RI on Monday, April 21, 2008

Anyone remember the clarity of reception they had with the "Sportster 1 or 2"?
Well The FCC stepped in and downgraded the FM broadcast capability for the Sportster 4 Sirius units.
Sirius tried to put a package together to get clear reception via a FM station with a inside the car antenna contraption. It did not work.

Well here is the solution. Clear reception for the "Sportster 4" receiver.
Finally crystal clear sound.
Don't wait to decide later if you should or should not get it.
Buying a Sportster 4 or Starmate 4 - Simple answer GET IT.
This is easy to install with the step by step Crutchfield directions. No need to fumble with the terrible antenna contraption that Sirius includes.

As usual 100%+ satisfied with Crutchfield.

Made all the difference

Written By Devin, Carlsbad, CA on Friday, January 11, 2008

Crutchfield Customer Review (What's this?)

I received a Sirius Sportster receiver as a gift this Christmas. My car stereo has no auxiliary input jack, so my only option was to use the FM transmitter. Unfortunately, the FM transmitter in my Sirius receiver is nowhere near as strong as previous Sirius models. Apparently something to do with FCC regulations. Basically, the sound quality with the standard FM transmitter was so bad (weak signal, lots of interference), I was ready to ditch the whole thing. Then I found this device. After a 30 minute install, I am getting full, crystal clear sound. I was skeptical that it would work this well, but I am now a believer.

Must have for newer Sirius radios

Written By Marshall, Joppa, MD on Friday, November 23, 2007

This is a must have if you are buying a sirius radio and your factory radio doesn't have aux. inputs. I replaced my old visor radio that would broadcst an FM signal a block away with a new sirius radio. The radio came with an antenna and suction cups and sounded like an am radio in the basement of a bomb shelter. With this unit installed no more searching for a clear frequency and the sound is great albiet a bit bass heavy which can easily be adjusted. This should come as standard with the new sirius radios since the FEDS made them reduce the FM output.

Crutchfield Customer Review (What's this?)

This is a great solution to the recievers that have the weaker transmitters. I have a starmate replay and was very dissappointed in the sound quality. Stations were being overidden with other fm stations. I spent more time hunting a clear channel. I installed this product and the difference is night and day. The Crutchfield team did a great job assisting me when I ran into a problem with the install. All and all I believe it took 20 to 30 minutes. Great solution. If you have sirius this is a must!

Easy Install, Great Sound

Written By gfzyriek, Memphis, TN on Thursday, June 21, 2007

2005 Toyota Sequoia with navigation. No cassette deck where I could use adapter and wireless FM modulator did not work; plus those sound horrible.

Crutchfield master sheet made install a snap (I'm terrified of taking apart my car's dash so you know where I stand technically). Took me about 20 minutes to install since I was being super careful.

Sound is great though a tad bass heavy.

Still tinkering with radio frequencies because I get some interference on some "dead" stations but mostly get a great clear signal.

Night and day difference for the better. I'm no longer 'blown out' by big trucks or remote FM broadcasters. Finally, clear reception!

Works well for Sirius

Written By Benedict, Indianapolis on Saturday, June 16, 2007

Unit works great for sirius radio. Problem is now my normal FM channels and AM channels come in much worse. I have reinstalled twice and cannot receive any AM stations. Normally can pick up AM all the way from Chicago. It does work very well if Sirius will be all you are listening to.

I'll try reinstalling one more time to make sure factory antenna lead is inserted all the way otherwise I'll probably return and get a head unit with an auxillary input.

Simple solution for a big problem

Written By Kevin, Central California on Thursday, May 31, 2007

This is an excellent product. I travel over 2000 miles each month, taking me through many areas which makes setting one station for my modulator very difficult. With this simple product I now travel worry free, and never have to switch transmit and receive channels, the sound is crystal clear.

When I first installed my sirius starmate I was very disappointed with sound quality.No matter where I tuned FM noise was dominant and annoying.I did some research and found the sirius fm direct adaptor on the crutchfield website.My order came very quik and was very simple to install with the free info and inexpensive stereo removal tool from crutchfield.I turned on my stereo and was amazed with how good sirius sounded now!I never have to switch fm channels while driving to get excellent reception.This little black box is the hot setup!

Poor frequency response

Written By Louie, Arizona on Thursday, March 15, 2007

I have the Sirius One plug and play tuner and let me start off by saying that the built in wireless FM transmitter is completely worthless, at least in the Phoenix metro area. I hoped the FM Direct Adapter would solve the transmission problem and it did, but not completely. As all other reviews say, it does eliminate static and interference from other FM broadcasts. However the frequency response is very limited, particularly across the high end. No treble at all when compared to the sound quality of the FM stations. Has anyone else noticed this? It's ironic that the tape adapter (which IMO provides better sound) suffers from a lack of low-end punch -- wish I could combine the two. Another problem is that the Satellite tuner gain cannot be adjusted enough to match that of the FM stations (this is with a 2000 Isuzu factory head unit). I know there is another product for this but why bother. I will be returning the FM direct and buying an aftermarket Sirius head unit.

FM Direct Adapter

Crutchfield Customer Review (What's this?)

Before I bought this, my SIRIUS Sportster 4 radio was always full of static. I had to change stations several times during my commute to work.

I installed the FM Direct Adapter last week, and since then, I haven't had to change the station once. Even when went on a 600 mile trip over the weekend, my reception was crystal clear the whole time.

Works great in X-Type

Written By Henri, NJ on Friday, February 23, 2007

I use this in my X-type. Wireless Transmitter worked, but I was getting annoyed by the hissing noise. After I installed this the sound quality is much better.

I use it with a strong local station so I don't lose a preset on my radio. When used with a weak station vs. a strong one, I haven't noticed a difference, so I keep it on the strong one. That way when I turn of my Sirius (which never happens) I can listen to that local station.

You will need adapters for your X-Type...Crutchfield has them.

Crutchfield Customer Review (What's this?)

This is great. I had terrible reception in my 2001 Dodge Pick up. Installation took 20 minutes from start to finish. I highly recommend it. I wish that Sirius would include it in each receiver. I have no static now.

So essential, so easy, so great!

Written By robbie, Atlanta, GA on Sunday, February 04, 2007

After receiving a Sirius S50 player for my car, I had to figure out the perfect way to get the best reception. It seemed that the FM signal could only be picked up whenever I had my hand on the player. As soon as I removed my hand, the signal would be lost and interfering static was very obtrusive and annoying. After getting this product (FM Direct Adapter) from Crutchfield, not only did I get a cheaper price on it than most retailers around my part of town, my satellite radio reception in my car has been pristine! With the included directions from Crutchfield, installation was literally done in less than 10 minutes with my 2002 Nissan Sentra and I really couldn't ask for more, considering places around town were charging $30+ for the adapter and even more money for the installation that, at some places, "would take all day." You just can't go wrong with this product, and getting it from Crutchfield makes it even sweeter! Thanks so much!

Must Have For Any Sirius Receiver

Written By Ilya, Northeast Ohio on Sunday, January 28, 2007

Crutchfield Customer Review (What's this?)

Must have if you are installing a satellite radio in your car and you do not have AUX input in your car stereo. The reception quality is great, but you have to remember that the FM modualator will not give you full satellite radio quality since it uses FM reciever to relay the signal instead of true direct connection.

From terrible reception to incredible

Crutchfield Customer Review (What's this?)

I used this adapter to connect my S50 to my '92 GMC pickup. The S50 without the adapter had terrible reception. I then hooked up the little hanging cord antenna that came with the unit, and that helped a little, but even then the reception was only ok. I then decided to purchase this adapter. I hooked it up today and it works fantastic. I have the factory radio unit in my vehicle, so I can't compare it to CD quality, but if it isn't CD quality, it is really close. I sounds great with the speakers I purchased and installed. I had to buy antenna adapters to plug in the adapter, so it ended up costing me about $40 for the whole package ($10 for each antenna adapter and then the $20 for the Sirius adapter). It was well worth the money.

Installation was ok; not extremely easy, but not super difficult either. I had to remove a platic panel below the steering column and remove the ashtray. I had decent access to the stock radio connections that way.

Must have for all Sirius Installs

Written By jimmd36, New Jersey on Saturday, December 09, 2006

Like the other poster I had terrible reception. I have a BMW and had no idea how to take out the stereo so I paid $100 to have the modulator and my starmate wired in. The modulator is a MUST have for any sirius install. Quality is 100 times better. have the radio pick up the signal through the air just doesn't work if you are near a city.

If you're thinking about it ..... BUY IT!

Written By James, Nashville, TN on Tuesday, December 05, 2006

I was doubtful at first. How can this little black box improve what I thought was an acceptable listening experience? Is it CD quality? - No. But I really did not realize how much background noise was present using the regular FM transmitter.

I used this on an XACT XTR7 in a 2001 Tahoe.

This adapter plugs in line between your antenna and the head unit. When the Satellite Radio is switched on, it cuts out the signals received from your antenna. Only the strongest of signals will come through. So tune in to a frequency that is not used in your area and enjoy.

Easy to install - I was done in 30 minutes even after battling with the radio.

It is too bad that this is not standard equipment with the radio itself. I have had this radio for almost 2 years. Now it feels like it is brand new all over again.

FM Direct Adapter

Crutchfield Customer Review (What's this?)

Before purchasing this product, I was disgusted with my Sirius Sportster Replay. I could not tune my factory radio to any station to listen, without horrible static and interference. After purchasing this product, GREAT! NO MORE STATIC! Would recommend this product to anyone wanting Sirius. Installation was simple: Just pulled out factory stereo, plugged wire from fm antenna into the adapter, plugged antenna wire from adapter into factory radio fm input, and plugged the other wire into the Sportster Replay's docking station. About 5 minute intstallation. Thanks Crutchfield, for recommending this much needed fix. NOW I ABSOLUTELY LOVE MY SPORTSTER REPLAY!!!

This solved all my problems for my Sirius Radio

Written By Garnett, New Jersey on Tuesday, November 07, 2006

I was having numerous reception problems with my Sirius Starmate, when using the built in FM transmitter to my radio. Reception was nothing but terrible, lots of static & noise. Living in the NYC/Metro area, its difficult to find an empty frequency. After doing some research on the site here I discovered this adapter. After an informative online chat with one of Crutchfield's helpers, I quickly bought this adapter & installed it.

Installation was easy, simply remove the existing antenna that feeds your radio and insert it into the adapters input, re-insert the adapter's output antenna into the antenna jack on your radio and plug the mini connector into the FM Out jack on the Sirius radio. What a difference it made!

Installation took a total of 5 minutes, although it was probably made easier due to the fact I already have an aftermarket radio that uses a DIN shell. If you have an aftermarket radio that fits into a DIN shell, installation will be fairly easy. If you have a factory radio it may be a bit more difficult and time consuming.

I'm now enjoying much better sound quality as well as noise free reception. As someone else mentioned in another review, this adapter should be included with all Sirius radios. Thanks again Crutchfield!

Product Research


Overview: The FM Direct Adapter is a hardwired FM adapter that allows you to feed the signal from the FM output jack on your satellite radio receiver into your car radio via the antenna connection, eliminating the outside static and interference you sometimes experience when using a wireless FM modulator. You also get to keep your local AM and FM stations when your device radio is turned off.

Note: This FM Direct Adapter is not a stand-alone FM modulator and cannot connect to the headphone or audio output of other external audio sources; it must connect to the 2.5mm FM output on a compatible satellite radio receiver.

Connections: The FM adapter box features the following connections:

  • To Radio: Male Motorola antenna plug on a 18" cable, plugs into the vehicle's AM/FM radio antenna input
  • To FM Antenna: Female Motorola jack on the side of the switch box, accepts the vehicle's antenna cable
  • Antenna: Male 2.5mm mini-jack on a 21' cable, plugs into the FM Out modulated output on the car kit

Dimensions of FM adapter box: Height = 1.25", Width = 1.875", Depth = 1.8125"

Installation: The FM adapter box is typically mounted behind the dash, near the radio. In this case it's likely that no antenna extension cable will be needed.

Antenna Adapters: Some vehicles (such as select GM vehicles, Volkswagens, Nissans, etc.) may require antenna adapters in order to connect the FM adapter Box to your vehicle's OEM antenna connectors. Please consult the Outfit My Car section of the Crutchfield website to see if OEM antenna adapters are needed.
