Looking for a way to connect the audio from your DVD system, satellite radio tuner, or portable music player to your car radio? No worries, the Scosche FM-MOD01 FM modulator offers an inexpensive solution. It converts the audio signal into an FM signal which will play through any factory stereo — no auxiliary input needed, all it takes is an FM radio!

The 40" power/ground wire has an in-line On/Off switch (which can be mounted in a convenient location). Connect your vehicle's antenna lead to the FM-MOD01 and run its 21" antenna cable to the antenna jack on the back of your radio.

Just plug your source into the FM-MOD01's pair of RCA inputs and tune your FM radio to the selected frequency. You can listen to the audio signal from just about any source — a videocassette or DVD player, MiniDisc, CD, or MP3 portable, anything with a mini-jack or headphone output. A switch allows you to choose between two different modulation frequencies (87.9 MHz or 88.3 MHz) for the best possible reception in your area.

Scosche FM-MOD01 Modulator

Written By Ryan, Christiansburg, VA on Tuesday, February 03, 2009

Crutchfield Customer Review (What's this?)

Great product. Installed quickly with the help of the Crutchfield Master Sheet. I was able to turn the toggle switch to the 'On' position, and tuck all the wires, switches behind the fuse panel, so everything is hidden out of view. The only thing that is visible is the audio cable to hook up my wife's iPod. Sound is crystal clear, with no static. The only hiccup I see is the need to turn the volume on the iPod to maximum, while the master volume on the head unit is about half or more. But this may be personal preference. I don't necessarily blast the music, but I do like to be able to hear it above a whisper. Overall, great product. Highly recommend.

My Doughter attends school in Los Angeles and there are no available frequecys for her Ipod transmitter. This product was the fix. This modulator is very affordable and works well. Now she can use her Ipod again. She is very happy. I also put one in my old Lexus. It's working great as well, so I'm happy too.

Crutchfield Customer Review (What's this?)

I got this product because I didnt want to buy an expensive aftermarket stereo for my car which doesnt have an auxillary input for my ipod. I tried 2 other FM transmitters and honestly, it was a waste of money not to mention annoyance. The installation was not too hard with the mastersheets that Crutchfield supplied. The sound is pretty good, not the best (some slight interference at times) depending the area I guess, but it is definitely much better than my previous 2 FM transmitters and well worth the price. I also agree what others have said that the volume is lower through the device so you have to crank up your stereo volume higher than normal.
Overall, its a pretty good product. I would recommend to anyone who is thinking about getting a FM transmitter for their iPod or mp3 player.

Written By Stephen, Long Beach, CA on Wednesday, January 28, 2009

Crutchfield Customer Review (What's this?)

I installed one of these in my 2004 F-350 and one in a 2005 Mustang. They work as advertised. You do need to turn up the volume settings on your iPod and the radio. You will also learn to turn both down when you shut down or you'll get surprised later!!

The installation was easy with simple hand tools. The only difficult part is getting an exact size hole in the dash for the switch. Drill it undersize and bring it to final size slowly with a file or die grinder. You don't want to go oversize on this by mistake or your switch will fall out of the hole.

Works Great!!

Crutchfield Customer Review (What's this?)

I installed this unit in my GF's 2003 Xterra because there was absolutely NO other way to do so--in her Xterra with the Rockford Fosgate 6-disc audio system, there's no way to hook up an aux input other than an FM modulator like this unit.

And it works great!!! Installation was a breeze with the instructions provided by Crutchfield. I've installed units like this before so I didn't have any trouble, but literally ANYBODY could do this, especially with the pictured instructions in-hand.

The only cons that I can find are two things: the green LED light for the on/off switch is way too bright, especially at night. I would recommend getting another switch from on outside source ... any 12V switch will work. And, lastly, TURN YOUR RADIO DOWN BEFORE YOU SWITCH THE UNIT OFF!!! When you turn the unit off (depending on what kind of MP3 player you use) the radio will turn on instantly and if you have your volume up it'll be BLARING!

All in all, a perfect product that works flawlessly and delivers CD quality sounds through the radio!!

This is a great product for the money. I've used several wireless ones in the past and none of them worked well as well as this wired one. This was such an easy set-up. I really wish that I did it earlier. Thanks for the help Crutchfield.

Sounds good, hope it lasts

Written By Greg, Pittsburgh, PA on Tuesday, January 27, 2009

Crutchfield Customer Review (What's this?)

The sound quality of this product is its best feature and truly what matters, but I question how long the unit will last. The power wires are extremely thin, 20 gauge or thinner and quite fragile as a result. Fragile as in hard to strip the outside of the wire without snapping the core!

The "on off" switch appears to do nothing according to my volt meter so I have no idea why it is even included - whatever you do don't drill a hole in your dash for it like i almost did before testing it, just leave it in the on position and tuck it into the dash. The switch should also be lighted to show whether its actually on or off in my opinion as well.

But, after all its short comings design wise, the sound quality is as expected so I wouldn't steer someone away from buying it completely. I just wish it was built a little stronger so make sure you mount it well so the weight of the unit doesn't tug on the wires. I get the feeling that a few tugs on the wires from the unit not being securely mounted would result in a non functioning unit.

This item never worked out of the box, so i called the 1-800 number on the box and they told me to go return it and they would waranty it out. Well I already had a complete set of speakers that did not work from Crutchfield and was told i had a bad amplifier,thats why my speakers were not working, I could not find anyone locally that could waranty this,I knew the odds of getting anything else fixed was out of the question. so i went to the local audio store to purchase a diferent brand modulator. Its still working just fine.

Crutchfield Customer Review (What's this?)

I got this product because I didnt want to spend the money on an aftermarket stereo for my car which doesnt have an auxillary input for my ipod. I tried several different FM transmitters and they are a huge disappointment, then I found this device. Installation is pretty easy with the mastersheets that Crutchfield supplies, otherwise I would have ripped my dash to pieces trying to figure out how it comes apart. The only problem I ran into was figuring out which wire was the 12V power supply to the stereo, but a few minutes with multimeter solved that mystery (it would be nice if Crutchfield could add a wiring diagram to their mastersheets). The sound is good, not great, and there is some slight interference at times; but it is definitely better than any FM transmitter and worth the price. Like others have said the volume is lower through the device so you have to crank up your stereo volume pretty high to get it loud enough. Its also kind of a pain to have a power switch to fool with, though you can leave it on all the time if you don't mind losing that radio frequency permanently, I don't.

Overall, its a good product. I would recommend to anyone who is thinking about getting a FM transmitter for their MP3 player.


Written By Christina, Deltona, FL on Thursday, December 04, 2008

I wasn't able to replace the unit in my car or it would destroy the dash layout in my 2004 mazda 6. I got this product within a few days and took my car's center console apart and got to work. Luckily, I did not need an adapter for my car. The instructions that came with this product were specific to my vehicle's interior setup - which was fabulous. It gave step by step instructions on how to disassemble my vehicles dash panels to get to the radio and take everything apart. I have NO knowledge of the wiring or how to mess with the components of audio systems. With this said, I had to call customer service to get info on what wires to cut to splice with the product's wires to make a connection with my stereo. The crutchfield rep walked me through the process and got me up and running with great help. Since I had no idea what I was doing with the wiring thing, it took me longer than I had expected to get everything going, but the pay off was SO worth it. I didn't have to drill holes or modify my car's interior (other than splicing wires) to get this to work. I had to turn up the volume on my mp3 player to hear any music but I don't need to use the on/off switch that came with the product. It turns off when I turn my car off. The music is crystal clear - CD quality sound - better than I could have expected, really. No whistling or whining between songs as other people have stated that they hear. This is a great product and I couldn't be happier.

Definitely enjoying my MP3 player in the car with this product! The sound is as good or slightly better than the FM signal on my radio - quite satisfied. The installation was straightforward, though instructions were in Spanish(?). The technician at the 800 # was extremely helpful with identifying the power and ground wires on the receiver wiring harness. Very happy with this purchase.

Better than any FM Transmitter

Written By Douglas, Troy, IL on Thursday, October 23, 2008

Crutchfield Customer Review (What's this?)

This product works great! I have tried several FM Transmitters for my iPod and all had a great deal of static with very low music quality. I found that I had to change stations all the time to try to find a clearer signal. After an easy install, I have crystal clear music coming through my speakers. If I didn't have to deal with an on/off switch, this would be a 5 star rated product. If you don't have any other way to directly connect your iPod through your stereo, this is the easist and cleanest sounding product I've found.

Crutchfield Customer Review (What's this?)

I ordered this product and it came within a few days. I had a local stereo installer put it in for me. I cannot stop using it. The sound is clear with no static, etc... I needed antenna adapters. It is totally hidden and the wire is coming out through the ashtray. The only thing I notice is that when I turn off the ignition, I have to remember to turn down the volume first, b/c the FM radio jumps in for a bried second.
I am happy with it and am ordering one for my other car.

Was looking for an ipod interface for my wife's Mazda 626 (02' model) but there wasn't one available. Crutchfield offered this product as a solution and the installation guide to go with it. Installation was easy and the sound quality is great. No buzzing or interference...this beats hands down any modulator/transmitter on the market. Don't waste your time buying any other transmitter besides this one...seriously.

Scosche wired FM modulator in C5 Corvette

Written By Frank, Greensboro, NC on Friday, September 26, 2008

Crutchfield Customer Review (What's this?)

At long last! I'm playing my portable XM radio and iPod through my factory stereo in my 2003 Corvette convertible! After searching high and low for a solution to my desire to play auxillaries through my stereo, I contacted Crutchfield via email. They responded in detail with two options, one of which I chose, purchased and installed. And it's great! Affordable, easy to install, and sounds just fine. I can't say that the iPod playback is CD quality, but it's sufficient for cruising with the top down! Only reason for the four stars rather than five, the unit is brand new and my experience with it is limited. Thanks, Crutchfiled (Lyle) for the great service!!

Crutchfield Customer Review (What's this?)

Installation was simple since no adapters were needed for my mazda 6. Hooked it up and works like a charm. Small and compact so easy to stash behind dash. As with anything coming through radio stations, small amount of static, but crank the tunes and you can't even notice it. If you need something quick and not costly, this is the answer.

Cleanest Signal Ever

Written By Phillip, Chattanooga on Friday, September 19, 2008

Crutchfield Customer Review (What's this?)

98 Honda Civic EX coupe - I use this device everyday on my 1 hour commute to and from work, I used to have a standard FM transmitter, it was an ok solution i.e. lots of static, and noise. When I installed the Scosche FM modulator I had high expectations, and they were met, during my drive I had none of the troubles from my previous transmitter, and the clarity was great.

The 2 reasons it did not get five stars:

1) No mounting brackets (I had to tie wrap it) it's snug, but I would have liked to bolt it down.
2) This is a problem with most transmitters - you have to turn the volume of your source audio way up to get a clean signal.

I am very pleased with this product and have recommended it to others who do not have an easy AUX input option.

Great and simple

This was an easy installation and works great! Flush mounting the switch was the only tricky part, I should have made sure I had a 3/4" drill bit before I started. Overall, I am satisfied with the product and I'm glad I can listen to my sat. radio with clarity now!

Great buy!

Written By xaenon, Cincinnati, OH on Tuesday, August 26, 2008

Crutchfield Customer Review (What's this?)

This is an excellent little gadget for the price, and it works very well. Installation was super-easy, only two wires to hook into the wiring harness and the rest was plug-in connections. If you've ever installed a very basic car stereo, this should not be difficult at all. Sound quality is pretty good, far better than those 'wireless' gadgets. Some models may require antenna adapters but these are easy to get. My only gripe is that the audio output is a little weak - but that's more an issue with MP3 players than it is with this device, because MP3 players, particularly the cheapies, are notorious for weak output. Turn up the device to max and crank the volume on the radio, though, and it is pretty decent.

As I Expected...

Written By Jerad, Iowa on Monday, August 25, 2008

Crutchfield Customer Review (What's this?)

PROS: It works MUCH better than any FM transmitter that I tried; inexpensive solution (unless to have to buy antenna adapters); good solution for those wanting to keep their factory stereos.

CONS: It has a power auto-on sensor would be nice; power and input leads could be a little longer; unit could use more signal gain, so I wouldn't have to crank up the volume so much; antenna adapters can effectively double the price (sorry Bose owners)

No English Instructions

Written By Greg, Northbridge, MA on Saturday, August 16, 2008

Crutchfield Customer Review (What's this?)

I installed this product in August, 2008. I use it to connect my iPod to the factory stereo in my 98 Dadge Ram van. The unit performs exactly as advertised. The sound quality is good, but as expected it is limited by its use of the stereo's FM tuner. It does not suffer from cell phone interference as did the cassette adapter that I had tried.

Fortunately the installation was pretty simple because the Spanish only installation instructions were useless to me. The hardest part of the installation was mounting the on/off switch.

Had the product come with instructions in English I would have rated it 5 out of 5 stars.

Good product for the price

Written By Cory, St Paul, MN on Monday, August 11, 2008

Crutchfield Customer Review (What's this?)

I replaced a direct-wire Sirius FM modulator with this Scosche unit. The Sirius direct wire adapter would not provide a strong enough signal to give me enough volume with the top down in my convertible. The Scosche unit provides a stronger signal and adequate volume so I can blast the stereo with the top down. Installation was about what I expected - there are a lot of wires to manage and finding a place for the on/off switch was a bit of a pain, but the on/off is important because you have to turn off the FM modulator if you want to use your regular radio. All-in-all, I'm very happy with this product, especially given that my other alternative for direct connection of Sirius to my factory sound system is a $400 fiber optic adapter.

Performance Surprise

Written By united9198, Wisconsin on Wednesday, August 06, 2008

Crutchfield Customer Review (What's this?)

After just about giving up on the idea of using my iPod in my Chrysler Crossfire roadster, I came across this item based on a recommendation from Crutchfield. I had tried two different FM modulators (both wireless) with very poor results, and had all but decided that I was out of luck. The difference with this unit is that it plugs into the antenna and sends a very strong signal to the radio that overcomes the stray radio signals that bedeviled the wireless units. I have tried several iPods and get great results with all of them, including the original shuffle which is small enough to keep right in the car.

The only negatives are the requirement to buy a couple of expensive antenna adaptors so that it would work with my vehicle. While that works well, it does add $ to the cost and that would not be necessary if there were a simple adaptor kit included. I also had a problem with the cheap switch and had to buy a replacement, but otherwise this was easy to install and works like a champ.

I can run down the road with the top down and tunes cranking without distortion or excess noise. This is a great solution for those who just want to plug in the iPod and plays some songs.

Scosche FM-MOD01 Modulator

Written By Jimmy, Houston, Texas on Tuesday, August 05, 2008

Crutchfield Customer Review (What's this?)

Great product for the price! I put one in my daughter's Jeep Liberty so she could use her ipod, and she LOVES it. Although we read reviews where there can be a static noise in between songs, she still wanted it. After installing it, we heard no static whats so ever. Great sound! I did have to buy two antenna adapters for her jeep. This one I had bought from a competitor, HOWEVER, it didn't come with specific installation instructions for my vehicle, so I had to search the web to find how to take out the Jeeps radio correctly, plus didn't know that I would need antenna adapters.

My wife liked this product so much that she wanted one in her Kia Sorento (no antenna adapters needed), so this time I ordered it from Crutchfield because you can email them before ordering and they can tell you if you need antenna adapters or not, plus include them in your order. Also, they send you specific installation instructions for your vehicle (except for radio wiring diagrams). This is all worth the few dollars more I paid compared to the first one I bought. LESSON LEARNED!! My wife's Sorento doesn't have any static between songs either. Even if it did, for the price, who cares!

Thanks Crutchfield!

I just bought the item today. I was able to install it in about 30 minutes. The item works very good for listening to music, and as a added bonus, i can use it to make phone calls with my cell phone while driving. The sound quailty is not as good as an direct aux input, but for not having that option at this time, this will allow me to listen to music, and to use the radio as a speaker phone.

Exactly What I expected

Crutchfield Customer Review (What's this?)

This product allows an Aux Input for my factory Honda radio that did not include one. Sound quality is equal to an FM radio station broadcast, maybe better. I purchased it to connect my Garmin GPS unit so I can play MP3 audio and hear voice commands over my car stereo and not have to constantly search for an unused radio frequency.
Not related to this product - The free instructions
provided by Crutchfield for a specific vehicle model makes the installation simple with basic tools. These instructions are invaluable to individuals not
familiar with the assembly of automobiles. No need to call tech support on this.

Inexpensive Plug-and-Play solution

Written By Spike, Boston, MA on Monday, July 21, 2008

Crutchfield Customer Review (What's this?)

I bought this for my '04 Mazda 6s (Bose factory system), having given up on finding any type of adapter that would let me plug an 8th-inch aux mini-jack directly into factory receiver through the (unused) tape input. I installed the FM modulator last week and I am very happy with the results. Sound quality is very good - not CD, but you shouldn't expect that from an FM modulator. Still it is much better than any wireless transmitter I have used, and I would guess its quality is probably more than adequate for 90% of drivers. You also don't have to change stations - I've found so far that even a strong radio signal on the same frequency will not interfere noticeably with the direct line through your antenna input.

Installation was fairly easy, especially with the Crutchfield instructions, although you will have to go to your local electronics store and find a way to run power to the unit. I bought a cigarette lighter adapter and crimped it to the FM modultor power wires.

If this thing was $100, I still would have bought it, and probably given it 4 stars. But for the price it deserves 5, easily. I highly recommend this product to anyone who can't find a direct line input to their factory receiver.

should've just got a new stereo

Written By greg, chicago on Monday, July 21, 2008

Crutchfield Customer Review (What's this?)

PROS: You get to keep the aesthetics of your original factory stereo (including steering wheel controls). Device hides behind dash of vehicle. No need to constantly change stations while driving between cities (as with non-wired FM transmitters). you can run any length standard audio cord to your device.

CONS: Device cannot control or charge MP3 players. Improper installation could result in interference. You may need additional accessories and knowledge of vehicle's electrical system.

SOUND QUALITY: Almost as good as commercial FM broadcasts.

INTERFERENCE: Needs to be kept away from engine area. Picks up GSM cellular activity if phone is close to device or its wires.

INSTALLATION: Cruchfield instructions were very helpful for opening dash but did not elaborate on
electrical connections. Took me about an hour to put it in.

My thoughts: After shelling out so much for this device and the related accessories, I wish I had just put in a new stereo. I see ones on here with the iPod interface. It would be worth it to keep your eyes on the road and not be looking at your iPod while you're trying to drive. There also wouldn't be the clutter of charges, remotes, etc.

For the price, sound quality, and ease of installation this is the best I have found if you have no other options for attaching an i-pod to your stock receiver. Installing this in a 06 Nissan Altima took about 45 minutes. The sound quality of this does not even compare to a wireless FM transmitter.

Crutchfield Customer Review (What's this?)

I bought this for my 2006 Subaru Outback (LL Bean edition). Because of my car's automatic climate control, I cannot install any after-market radio--a major drag. Justin from customer service steered me from a radio to this product and the two adapters required. Some quick checks on Outback enthusiast websites confirmed that this type of FM modulator was the only option.

I can't speak to installation since I took it to a shop to have it installed.

The sound quality is only OK. The volume is very low, so I have to crank up my radio's volume to hear anything. Only the very clearest podcasts come through clearly. I have a few podcasts of old time radio shows (admittedly not good recordings), and I can't hear them clearly at all. The sound quality is also....I don't know, shallow. (I'm not a car audio person, forgive the description). The highs and lows are lacking. I've always been perfectly satisfied with the factory radios in my cars but I was a little disappointed in this unit's sound.

The bottom line--if you can afford a radio with and iPod aux plug *and* your car can take it, definitely go that route. This option was cheap, and adequate--but not much more.

Could be better

Written By Mark, Kansas City, MO on Monday, July 14, 2008

Crutchfield Customer Review (What's this?)

Bought this to hook our XM radio into our factory stereo. Easy to install and it works ok, but could be improved. There is a switch to turn on the input signal. It should internally just check for an input signal and enable it. If I turn off my input source, then it should enable the FM antenna again.

For the first few days, it sounded decent. Then we started to notice a high pitched whine. The whine was worse when we accelerated. Not sure what would cause this. Wish I would have kept all of the packaging so I can return it. At least it wasn't very expensive.

Ended up buying the FM modulator made by XM. It doesn't need to be hooked into the power source and sounds much better.

Exceeds expectations when expectations are realistic

Written By Jesse, Whitewater, WI on Tuesday, July 08, 2008

Crutchfield Customer Review (What's this?)

The unit was relatively easy to install in my 2000 Chevy Cavalier. It took around 2 hours, most of which was spent taking apart the dash to access the factory receiver. For this car, two antenna adapters were required. I ran into a snag with having to wire the power to the fuse block; however, Crutchfield's excellent and fast customer service got me through it.

In terms of sound quality, it has exceeded my expectations; though, I did not expect CD quality, which it does not produce. However, it does sound relatively close to CD quality with only a slight attenuation in the extreme frequencies, with a more noticeable decrease in the bass frequencies. Just turn up the bass on your receiver to compensate. I'd say it sounds about as good as a high quality FM station.

The only minor issue I have is a significant drop in volume with the unit activated, which necessitates turning up the volume of either the receiver or the auxiliary device (e.g., iPod). I also need to find some way to mount the power switch (I need the sole cigarette adapter, which is a clear option).

I would also like to note that Crutchfield has among the best customer service I have ever encountered. They are fast, friendly, and very helpful. They have been gracious with returning a third antenna adapter that was recommended to me but not needed.

This thing does what it says it will do and is easy to install. It does have its limitations with a little bit of hiss between songs, but does a nice job and is a lot less expensive than replacing your entire audio system. Sound quality is pretty much CD level.

Scosche FM-MOD01 Modulator

Written By Mickey, Fredericksburg, VA on Sunday, June 01, 2008

Crutchfield Customer Review (What's this?)

Overall a pretty decent product. Certainly a better way to go to adapt an iPod to a vehicle with no aux plug (thanks, Porsche - not!) than a wireless FM transmitter. Sound quality is good, but not CD quality. It is certainly the cheapest way to get a wired hooked for your external music device to any system. The best thing I can say about it is: after a few miles down the road, you forget you are using an aftermarket product. I am very happy with it and the installation was easy (although some of the tech reps are not very familiar with this car so tech help on some minor questions was short of what I expected).

Sweet and Simple!

This Scosche is awesome! Not hard to hook up and works like a charm! The Crutchfield MasterSheet for my '06 Hyundai Sonata made the installation a breeze. Also, I have no hiss or background noise like others have mentioned. It's just simple and cheap...a must have when there is no factory aux. input!

Great option without AUX port, fantastic Crutchfield service and speed

Crutchfield Customer Review (What's this?)

Great sound quality and easy install! Much better reception than FM transmitters for the iPod. I have had 4 of those transmitters from various iPod accessory companies and they are all trash. This is a great alternative to those transmitters, with almost CD quality sound. For only $29.99, this was by far the best and cheapest option for me to feed my iPod directly into my factory radio system on my 2002 Ford Explorer.

Crutchfield got this to me in 2 days!! The Crutchfield Mastersheet was very clear in how to remove the console panel and radio on my car. I had to call in to technical service get a quick answer on the wiring of the 12V power supply and ground wire into the existing wiring on my head unit, but they knew exactly and quickly how to help. I spliced it directly into the head unit and didn't utilize the on/off switch because the radio powers off with the car. I simply hid the on/off switch with the other wires and the box behind the head unit.

Total install time: 45 minutes!

Other reviews note the need to increase your peripheral's volume when running the unit, which is true and you do get some increased gain, but cranking up the FM volume a bit and reducing the iPod volume fixes that. Just beware before switching back to other FM stations.

I highly recommend this product for its sound quality, ease of install, and Crutchfield support.

Recently I purchase and installed the Scosche FM-MOD01 FM modulator and
the experience was pleasant.

The instructions provided gave easy to follow procedures on how to
dismantle the existing factory radio in my 2003 Nissan Altima.

The installation of the Scosche FM-MOD01 FM modulator went smooth and
the clarity of the sound from my satellite radio and my iphone is much
better the Wireless fm transmitter that I was using.

I would absolutely recommend this product.

This items does a great job of doing what it was designed to do for a reasonable price. You can't expect crystal clear sound due to the inherent nature of this product's design, but overall, the sound quality is good. It was easy to install and now I can listen to my iPod without any major modifications to my factory radio.

Scosche FM-MOD01 Modulator

Crutchfield Customer Review (What's this?)

Best option for cars without AUX input.

I have 2002 pathfinder with in dash 6-disk changer, no AUX input. No one makes an ipod interface for this radio so I'm left with FM transmitter, FM modulator, or buy a new radio.

FM transmitters
Relatively expensive (compared to modulator) and they don't work well. The static is very annoying Too much static to be useful. Listening to static proved more stressful than just driving in silence. Don't waste your time. Resorted to listening to IPOD with earbuds.

New Radio
Didn't want to go the new radio route unless I had too. Concerned with functionality of steering wheel controls with aftermarket radio

FM modulator
This thing works great. Installed myself in about 1hr. Sounds incredible. Recommend you buy a longer connection cable to allow flexibility for connection.

Just installed this in my 2007 Jeep Patriot. Works great. The volume difference between the cd player/radio and satellite radio which i have plugged into the adapter are very close. A lot closer than the built in wireless fm transmitter. I mounted the switch under the cigarette lighter and the adapter on the other side of the shifter cover.

Crutchfield Customer Review (What's this?)

After buying and returning a few wireless units - including some that were twice the price - I gave in and went the wired route. GREAT MOVE. Easy to install, works great. Do I have the same fidelity of a cassette unit or in dash unit - no. Is it pretty close - Oh Yeah. I can't say enought about how easy it was to install using Crutchfields instructions. If I just had what came with the unit - I'd have pulled my hair out. Using Crutchfield's info sheet I had the radio out - this unit in and the radio installed again in less than an hour.
I should have bought this first.

Scosche FM-MOD01 Modulator

Written By Mark, Phoenix, AZ on Sunday, February 24, 2008

Crutchfield Customer Review (What's this?)

Like others, my experience with wireless FM modulators had been very disappointing, so I had fairly low expectations for this product, but based on the favorable reviews, I went ahead and ordered it. I'm glad I did! Installation was straightforward, the hardest part being working in the tight spaces behind the radio bay in the dash, and finding a place to put the on/off switch (I unded up removing the unused cigarette lighter, and using the hole which was almost the right size). Once installed, I found no FM bleed-through, nor was there any appreciable hiss or static when the MP3 wasn't playing. There also has been no interference or static noted while driving. There is a loss on the base end that is noticable, by since my factory radio has a modest equilizer, it was easy to correct for that. A simple bass/trebel adjustment would probably also do the trick.

You won't get concert-hall performane with this, but for what it is designed to do, I think it does it very well, especially at the price.

Installed in 1997 Range Rover

Written By dt, Austin, TX on Saturday, February 23, 2008

I just installed the Scoche FM Modulator in my 1997 Range Rover and am fairly pleased with the result, but not 100%. The installation was straight forward, although I needed to purchase the adapters for European style antenna connections. (Got them from Crutchfield.) The reason I'm not completely satisfied is that the sound quality is only fair. The sound doesn't come through as crisp as through a CD in my car changer or through the iPod headphones. Also, there is a background hiss or white noise, similar to what you get on some FM stations, but worse. It is less severe if you put the iPod volume all the way up and then use the stereo volume to control the sound level, but it is still definitely audible. (I even tried two different power and ground sources thinking it might be interference from a dirty power source.) I will keep the modulator, but was hoping to never have to use my CD changer in the trunk again...I'll still use the CD player more often.

Impressive product AND customer service!

Written By Jon, Birmingham, AL on Monday, February 18, 2008

Very rarely will I praise customer service for a company, especially in the modern age of "passing the buck" and offshore people who don't speak the language. Anyways, got this product for my wife, whose older car has no aux in port, but she likes her MP3 player and wanted to play it in her car. Product arrived, I opened the dash per the instructions Crutchfield sent (which are awesome, BTW), and had to call about the 12V wire. The CF rep was extremely helpful, since I'm not radio installation expert. He was able to point out which wires to splice together, and even mentioned an easy way to do it, with Scotchloks.

Beyond that, the product is also great! I have little to no background noise, it stowed away easily under the factory radio, and the sound quality is right at CD level. Great stuff, couldn't be more happy with the money spent!

I tried using a wireless FM trasmitter for my new MP3 player. That was a BUST! This product (although I did not install it) works wonderfully. I had professionals install it because I didn't have any equipment to do so, and it was just less of a hassel. However, the support from the Crutchfiled website was awesome! I did the internet direct connect and they set up a cart with everything in it that I needed, and all I had to do was pay! Awesome help and easy to use this site!!! I'm extremely happy with the end result.............clear music from my MP3 player in my car!!!!

Great product, need more info on installation

Written By Michael, Ohio on Sunday, January 27, 2008

Getting the product installed was the interesting part. I installed on a 2005 Honda Civic to work with a new Sirius radio receieved for christmas. The mechanical instructions from Crutchfield were great (I basically had to take the dash out), but there were no real instructions on how/where to hook up the electrical. I ended up blowing 4 fuses on 2 seperate occassions before I got it to work. Once connected properly, the unit is fabulous!

Excellent alternative for Ipod owners

Written By Doug, Harrisburg, Pa on Friday, January 25, 2008

Crutchfield Customer Review (What's this?)

I bought this unit for my wife's Mitsubishi. She has an Infinity sound system in it, which is extremely crisp. I was skeptical that an antenne-input system would give up on sound quality, since I had purchased a wireless hookup for myself and the sound quality was horrible. To my surprise and joy the sound is just as crisp as listening to a cd. The only slight drawback, and I'm being critical here, is the bass is dimished. Other than that I submit it as an option for Ipod owners who don't want to spend the hundreds of dollars for a factory made Ipod wiring harness. I may start selling it as an option in the car dealer service departrment where I work.

Written By Joe, Staten Island, NY on Wednesday, January 02, 2008

Crutchfield Customer Review (What's this?)

I've always thought these hardwired modulators worked fairly well. My mother had a car with an add-on CD changer that used an FM modulator and it seemed ok. I ordered this for my Saab 9-3 in a desperate attempt to get an Ipod playing through the factory radio. Installation was as straightforward as it gets. The performance however was lacking. I lost tons of bass response and the sound had a very "flat" feeling to it. Worse sound than FM radio stations. I also noticed a good amount of static/interference often while driving through certain areas. I checked the connections and they were tight and clean. It also does not work well with the Iphone, which makes tons of EMI by itself. Certain devices are succeptable to it and this is one of them. I ended up returning this product and will probably just replace the factory head unit one day.

Does the job

Written By Matt, Plymouth, MI on Thursday, November 29, 2007

Works great. You have to turn up the IPOD volume. I've played the mp3 player through aux inputs in cars before, and I am used to the fact that turning the mp3 player up to near full volume gives the best s/n at the radio. If you pause the mp3 player there is a bit of background hiss, but usually this is well below the level of what you would notice when the music is playing. It turns off with ignition so as to not accidently drain the battery, and all FM reception works fine whether it is on or off, but the AM doens't work when it is on.

Installed quickly in 2002 Focus with single cd radio. Dropping the glovebox by squeezing in the sides gave easy access to the right side and back of radio, so I just pushed the radio right side DIN clip with my thumb and the whole radio popped out with no tools required! The Crutchfield directions were great. I located the ignition and ground wires at the radio, cut back some insulation and soldered them on for a permanent connection and taped it up. I routed the switch into what might be an ashtray. I added a stereo headphone extension (recommended) to route the plug to between the seats and then the kids can use it to play videos through the car speakers from the back seat.

The installation was a breeze and the instructions Crutchfield provides for the installation process on my car were very thorough and accurate.

Reasonable solution for older stereos

Written By Tom, NH on Thursday, September 27, 2007

Crutchfield Customer Review (What's this?)

I was looking at replacing my stereo in my older BMW so that I could play music from my IPOD, but decided to try this adapter. For $30, you can't go wrong with it. My stereo had a CD changer port, but no other input, and this device worked out great. Once you have your stereo pulled out of the dash, you need to remove the antenna plug, put it into the device, and plug the device's antenna port into the stereo. You also need to find a place to put the switch. I read someone else's review where they wired the switch so that it was always on with the ignition. This is a bad idea. I found you need to turn the swith off to listen to normal FM stations; otherwise it is very difficult to pickup local stations. There's too much static. With the switch off, they come in clear. Also, I read a review where the person said the volume was very low using the auxiliary source (e.g. IPOD) vs a normal FM station. This is easily overcome. There is a gain control adjustment on the box. I turned it up to high, but found out it is easily and probably better sound quality to make sure the volume is up to max on the IPOD first. I think the gain control introduces some poor quality at the high setting. Realistically, it took me about 3-4 hours to do this, most of which was trying to get the stereo out, tapping into a pos/neg 12v source, installing the switch and dealing with trim panels so that I could get the input plug to my center console for the IPOD. All in all, it is an easy solution if you want to keep the factory stereo and/or avoid additional expense. Good luck!

Economical, high quality alternative to a new head unit

Written By Steve, East Windsor, CT on Tuesday, September 04, 2007

I was looking for a simple way to hook my Creative Labs Zen Nano Plus up to the Kenwood CD player in my 1977 Camaro, but not spend an arm and a leg, and not buy a new head unit. Rusty (Crutchfield Tech Advisor) suggested the Scosche FM Modulator, and it works perfectly. Inxpensive, works great, easy installation. I have no interference whatsoever, the sound quality is great for a $30 device. This product is perfect for the average person looking to hook an MP3 player to their existing stereo. It MAY not be adequate for the discerning audiophile, but for those with reasonable expectations, this is your product.

Great Solution.. OK Implemenation

Written By John, Long Island, New York on Tuesday, September 04, 2007

Crutchfield Customer Review (What's this?)

Product was fairly easy to intall (took a little over an hour from start to finish). There is however a background noise that is fairly loud when you use the modulator. The volume is louder than an FM Transmitter but is still lower than standard Radio or CD's. It did however solve my issue of losing my Satellite reception while using the Wireless FM Transmiter built into the Sportster 4. I also added a splitter so I can use it for my MP3 player as well. I can live with the lower volume but the background noise gets annoying especially when listening to Howard Stern or any other talk radio where there are periods of open air.

I just finished putting this contraption in my girlfriend's 2003 Ford Focus ZX5, reasonably easy to install once I got the information about the cars wiring setup from Crutchfield, just used some "Tap-in Squeeze connectors" to hook up the modulator's red and black wires to the appropriate wires coming into the stock Blaupunkt radio.

Works fine, once fixed

Written By Larry, Cincinnati, OH on Saturday, July 14, 2007

Crutchfield Customer Review (What's this?)

I'm no audiophile, but I did want to play my MP3 player through my car stereo. I hooked it up the best I could, but would get bad noise. One source was the alternator (when the MP3 was hooked up to the cigarette lighter), but there was another high-pitched noise that I couldn't get rid of. For two months I added filters, changed locations of grounds, played with the routing of the wires, to no avail. I was going to throw this one away and buy a new one locally. Since I had nothing to lose, I opened up the metal box and was surprised to see the quality of parts inside.

The fiberglass circuit board was third-rate and the chips were scuffed like they had been sanded. *Very* low quality. I was shocked. With the system on, I tapped the chips with a plastic pen and found the problem. Two large capacitors were touching. By simply bending them apart, I fixed the problem.

Now the system is great, and I agree with all the posts that say it gives great quality.

Highly recommended for stereo's without the aux in

Written By Amante, New York on Friday, July 06, 2007

I used to have another brand of these and did not worked well specially in the city so i was doubtfull to try this one. But since getting a Tomtom GPS with blue tooth for the cell phone i was in need to figure out how to send the conversation through the car stereo. So i decided to get this one after being convinced by the other reviewers here at crutchfield.

what can i say, got it during the afternoon hours i ate dinner then started working on this around 9:30pm finished around 11pm the hardest part is getting in to my car stereo but once your there hooking up this modulator is so easy.

the sound quality is very good and finally i can utilize the mp3 feature of my gps through the car stereo and at the same time speak hands free through the gps also and hear them loud and clear.

the only cons is the volume, you have to crank it up to normal level just to get a decent sound so make sure to lower the volume down before you switch back to fm or cd. but overall i am very pleased with my purchase.
