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.

Ok, I've had this product installed for nearly a year now and I can't believe I out up with it due to the consistently poor sound quality. No, not poor, HORRIBLE. I've stuck with it for a few reasons: A) the factory head unit that came with my '03 Subaru Outback sedan was large format and the replacement I had on-hand (a mid-range Eclipse with rear aux input) was standard size and I didn't want to have to buy and fit a dash pocket and B) the weather strip on my car makes a tremendous racket at highway speeds and it obscures any hissing anyhow, but really C) laziness; I just got used to working around it.No more! I went out today and replaced the head unit with the Eclipse and came right back to write this review (OK, I took a nap first). The Eclipse sounds wonderful and doesn't interfere with radio signals (which I actually don't listen to anyway, but the Scosche pretty much ruined even if I wanted to). As I previously mentioned, the audio hiss was terrible which meant that I had to set the Bass really high with the Mid and Treble low just so it didn't sound like an Edison Phono wax cylinder. This is on either frequency setting.I actually disagree with the assessment of some reviewers that this has better sound than an OTA FM transmitter... it's MUCH worse in my experience. This was bad enough but I was obviously willing to deal with it until the winter came. I live in upstate Ny and, though this hasn't been a terribly cold winter, the temp has been hovering in the 30's for a good few months. After I start the car, this piece of junk creates the most awful buzzing noise for at least a few minutes until some mysterious component warms up. To make matters worse, I have to have the stereo on as it doesn't seem to warm up unless it is actually powered.Now, I know what you're thinking, "BS, this dude obviously didn't wire it correctly." Not the case. All connections were soldered and the unit was properly grounded to the body (bare metal to a grounding bolt). Additionally, the connections have thermal shrink tubing on them. This thing just blows, period. Bad purchase.Oh, yeah, I forgot that the unit I bought was not the one I was shipped! It was the same basic unit with different components. Not a big deal, but I definitely had to rei agin my game plan at the zero hour.I've been thinking of writing this review every morning and cold afternoon for months. Man, it feels good.
