Best FM adapter I've ever had experience with. Totally shuts off the outside antennae, making for absolutely no interference, and plays whatever you plug into it. I plugged in a headphone jack adapter and now can plug anything I want into my what used to be non-AUX head unit.

Seller was 100% dead on with the description and received the modulator before Amazon's expected receiving date. Definitely recommended.

If you have any other option besides an FM modulator to do what you need to do, do it. An FM modulator should be a last resort. That being said, I don't think I could be happier with this product, given the fact that I had no other options.

First, note that this is a WIRED modulator. Wireless modulators are worthless in the US because of the FCC mandated limitations of their broadcast range. Wired modulators like this one tap directly into the antenna in your car and send FM signals directly to your head unit. As such, you don't have interference from other FM transmissions--like radio stations.

As far as wired modulators go, in the same system I tried a Kenwood FM modulator and one from Metra. Both sounded horrible for anything but audio books. I added a ground loop isolator to the Kenwood setup, and it sounded better, but it was still too painful to listen to music through the modulator.

This Audiovox system comes with its own ground loop isolator, and together they sound far better than any other combination I had tried. Everything about this setup is a little smaller than other options I've used, so they fit behind the dash better.

All in all, if you're looking for the best FM modulator on the market, I believe you've found it. AudioVox makes a bad situation tolerable, and in fact, quite enjoyable.

First i want to thank BeachAudio for thier fast and A+ shipping...Second the modulator was the modulator i ever use....no noise at all!!!!! and also has a switch so u dont have worry about the radio channel...use 89.10 Freq and you are ready to go...Trust me i am a happy customer you buy this product 100% worth the price...

I installed this in my 2007 Porsche Cayman S CDR-24, I had a Metra one before and it picked up alternator noise and was pretty noisy even with the engine off. This unit and its filters work really well. The alternator hum is eliminated. There is a quiet subtle noise when the car is off but it's not as noisy as the Metra unit. The sound from my MP3 player is a tiny bit lower. I do hear some distortion in the sound when music is an electric guitar playing very high notes. The Metra unit would distort the sound when a musician was singing high notes. Much better sound quality than Metra unit. I'm not sure if there's anything better than this. This is just a holdover until I get a carputer in there.

Easy to install and worked as advertised. If connected to power that does NOT shut off with the vehicle I suggest adding a small light to the switch to remind you to turn it off.
