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.

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.

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.

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.

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.

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.

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.
