Scosche FM-MOD01 Modulator Play Satellite Radio Tuner, or Other Portable Music Player Through Any FM car Stereo

Exactly what I needed, and it works perfectly. Sound quality is great with no interference. Simple to hook up (antenna in, antenna out, red (fused) power lead, black ground, and RCAs). If you have a factory radio without a CD changer input or an aftermarket radio with no auxiliary input, this is the solution. My only complaint is the power switch, but it's necessary because although this has a bandpass filter, some stations are slightly degraded outside of the band when the device is powered on. I'm not sure how this item has any reviews other than 4 or 5 stars, but those reviewers obviously didn't know what they were purchasing or how to use it and should not have left reviews on the product page.

Overall great for my needs - Make sure to use a clean dedicated ground (eyelet on a chassis ground), and DON'T use those cheap splice lock connectors, shoddy connection at best, cut your wiring with no connection at worst. The power wire is a small enough gauge to cut the ignition feed and use a proper sized butt connector with it tucked in the original wires. Pros: sound clarity is good, and drove 800 miles on 87.9mHZ frequency without hearing any stations over-riding my signal. Occasional popping when an outside station was broadcast at near stereo level/clarity on that frequency, but only noticed with the modulator on and no music playing. Price! With GM antenna adapters it's as cheap as the cheesy 12volt power source ones that have terrible reception. Near imperceptible loss of volume/signal if left on by accident when listening to other FM stations (although I haven't tried anything closer than 93.1mHZ) Cons: Cheap inline fuse holder, sheared the plastic tab off when putting fuse in, had to superglue together, if it ever blows I'll have to cut it out and re-wire a new fuse and holder. Noticeable loss of volume compared to FM or CD, if you don't have an amp for interior speakers it may not work for you. (volume at 100% with this on is similar to the volume at half with a CD in) On that note; Having volume set higher generates a small amount of noise, noticeable when musics not playing

It installed easily and works. But the audio quality is poor on either channel. Simple spoken voice is clear and easy to hear. But complex music, rock, etc, has a lot of distortion and sounds muddy. And higher frequencies (someone saying the letter "s" on a good clear microphone) ends up being a staticy hiss over the radio. Also, when the car has been parked in the sun for a while and the dash is good and hot, this thing's radio frequency seems to vary just a bit making the radio hiss and jump in and out of stereo until the A/C has run for a while to cool things down.

I bought this item for about $25 and went to a local auto stereo installation place. The installed it for me for $45. So for $70 overall, I got the mp3 input that I wanted, while keeping my factory stereo in my car. There is a black wire coming out of my dash near the electrical outlet, so it's not as inviting to a car thief to come and smash my window. Recently, my window was broken in a "smash and grab" and the FM transmitter iRiver AFT 100 Mobile FM Transmitter stolen. The FM transmitter was about $50, but the window cost $250 to replace. So having the factory stereo was very important, to deter car thieves. I don't have any static like I did with the FM transmitter. My car is a 2006 Hyundai Accent 4-door (Canadian made). My MP3 player is an iRiver Clix IRiver clix - Digital player / radio - flash 2 GB - WMA, Ogg, MP3 - video playback - display: 2.2" I put the volume around 20 on the Clix and about 25 on the car stereo, tuned to 88.3. The other stations still play clearly, whether I turn the FM Modulator off or not. If you want an inexpensive MP3 input, while keeping your factory stereo and a low profile for car theives, this is a good unit and I recommend it.
