Problem Solved!
if you have a noise you can't get rid of when you plug in your ipod or other device into the accessory jack on your car or motorcycle radio it is most likely caused by a ground loop. This WILL fix it!

I have a Mazda3 with the built-in aux input located in the console. Before I bought this, I could not charge and listen to my iPhone or XM Pioneer Inno without hearing that annoying buzzing that amplified the faster I accelerated...not an issue if running my devices from their own batteries. This device completely got rid of the interference and I can enjoy my tunes or Ron & Fez with pristine audible clarity.

I picked up this device because I can't get a good signal off my Sirius radio via the FM transmitter so I decided to try this on my audio input and it really works. The sound is crisp with no humming from the engine noise what so ever.

I am really happy with it..!

I was looking for something to eliminate the high pitch whine that I got from my Sirius radio, and this is it! Look no further, this is all you need.

I bought the PAC SNI-1/3.5 preamp noise filter about 6 months ago and have it permanently plugged into my car's mp3 outlet and leave my ipod plugged into it.... it eliminates all the nasty hissing I used to hear, I highly recommend this device if you experience any interference.

I bought this filter because of engine interference when I play music from my car. This filter filters out the vocals of my songs. It may work in other cars but it did not work as expected on my Corolla.

Works as advertised.. No more iPhone noise through the aux input in my car stereo.

This has working wonderfully in conjunction with my Syflex Auxmod installed in my 2008 Mazda 6. Perfect connection every time, no static.

we bought this item to eliminate the whining engine noise when using the aux port in our Mazda 3. I first thought there was something wrong with our ipod, but this completely solved our problem...no more whining!

Review written by DCR from Laurel, MD

Works as advertised, reasonable cost. I still now and then get a low hum (I use it to connect my iPhone to the aux input in my Prius), but it's hardly noticeable and nothing like how it was without this device. Recommended.

I purchased this on someone\'s recommendation so that I would be able to charge my mp3 player while running it through aux in my mazda3. It worked perfectly and solved my problem. I\'ve had it for 6 months and it\'s still working perfectly.

This was the absolute best ground loop isolator I've seen. It worked remarkably well on a computer that is in a vehicle. I thought I was going to have to take an RCA isolator and mod it for 3.5mm plugs ...not with these babies! Definitely would recommend and I would buy again if needed.

Whenever I plugged in my iPod to my car's AUX port, I got a lot of background buzzing. This product got rid of it completely.

I was getting a lot of whine with my Archos MP3 player. The SNI-1 completely eliminated all unwanted noise. I would recommend it highly!

Review written by XM Radio Owner from Rochester, NY

This unit works exactly as advertised. I replaced my factory installed radio because I wanted to get away from the low-fi FM modulator I was using to listen to my satellite radio, but the ignition noise was making me crazy. Then I found this gem! I saw the reviews and I must say, they were right on the money -- this thing eliminated the ignition noise with absolutely no negative impact on the audio quality that I could detect. It's worth every penny!

5 stars the whole way. Absolutely amazing product. I had a very high-pitched whine on my Sirius and TV inputs to a vehicle pc ... this completely eliminated them. Very satisfied, but more importantly, I am very impressed with Sonic's service. They processed my phone order in about 10 minutes, and I had these in my hands the next day by 10:30A ... all the way from the west coast! (I'm in NC) Hands down, excellent service and a great product!
