Highly recommend this product. Super easy to install and to operate. Sound quality is great. I've told many friends about this product. Way cheaper than buying new radio that has this capability.

This product works great. Very easy install. Great sound quality. Works flawlessly with my stock head unit.

-2005 Pontiac Grand Prix GT

So happy that I bought this. I now am able to plug in my iPhone to my car radio. I own a 2006 grandprix and there's no front auxillary jack. The installation instructions was easy. The agent was very helpful when I made the order. Would buy from Sonic for sure.

Very simple product to work with. Most difficult part was the removal of the radio from my vehicle to attach the device. Auxillary input allows the use of all sorts of digital devices through the stereo jack.

This was the only thing missing from my truck when I bought it, and it took about 15 minutes to install (minus drilling and adding the female plug in the center console for a cleaner look). It works prefect and makes listening to music so much more enjoyable.

I would absolutely recommend this to a friend (and already have) and I think anyone with a GM vehicle w/o an AUX input should have this.

4/5 on looks/design because its a little big for just a microchip and PCB, but there was plenty of room in a silverado dash so it didnt matter, could be tight in smaller vehicles.

4/5 on ease of use because it was a little confusing installing it, you had to flip something on pins depending on which buttons your dash had, not hard, but still a little confusing.

Bought this for my 2005 Chevy Impala. Works perfectly to use my cell phone as a music player. Very simple install.

Half an hour from screwdriver to music. What more can you ask?

There were only two minor negatives. The first is I thought the product operated on the AUX function in my Pontiac Grand Prix but instead its the XM preview funtion, but in my opinion its not a big deal. The second was finding the power supply. I ended up having the slpice it into the radio's power supply which took some work.

The positives are way better than the negatives. I love having the AUX port for my iPhone. Once it is installed it works perfectly. It is easily hidden and I ran the 1/8th inch cord without a problem. I suggest an extra set of hands for installation though, makes the process easier.

Having an older GM product without the capability to plug in an i-phone/smart phone or mp3 device into the factory radio, this device answers my problem. Was fairly easy to install although I found the instructions somewhat vague on how to operate the device once installed. Once I called the tech line, I was on my way to listening to Pandora in my truck.

Works great after you install it, just make sure you know what your doing and have a somewhat idea. The instructions weren't very helpful, but it was a simple installation. The connection is good and still runs great to this day (bought 6 months ago). Installed on 2004 GMC Envoy XL

I am very pleased with this connector, because now I can listen the music from my iPhone when I am driving. I recommend it for everyone who want to enjoy his own music.

Plug and play easy to install and set up. Fast delivery.

I searched a lot of forums to find an aux input for my 2003 Trailblazer stock stereo. Some websites report that this unit won't work on the 2003 without the satellite system, but that isn't exactly true. Anyone with basic mechanical and electrical skills can hook up this device. It took me a couple of hours to install it. It works great. On my Droid Bionic phone, I use an app called PowerAmp to play all of my music. It has a built in 10 band equalizer and the sound is incredible though the P.I.E. unit. Also, with the phone in its mobile dock, the phone becomes a great hands free, voice activated speakerphone through the car stereo. I highly recommend this unit.

The product works great and does everything I want it to do... when it works. One out of 5 times I want to use this product, it will not be recognized by my car and I have to shut it off and restart it until it works. Granted, it might be my faulty wiring skills, but I would like it to be more consistent. However, it is still less annoying than dealing with one of those radio transmitters, especially on long trips, and the price was reasonable. This is not really something the average person can install on their own, though. Took me about 3 hours from start to finish and I have experience taking off the dashboard and tinkering with other parts in a car. Just some stuff to keep in mind. Only owned for 6 months, therefore cannot rate durability.

I own a 2006 Pontiac grandprix. The stock radio doesn't have a connection for an external music player. I found this product by fluke while surfing the net. I followed the instructions which were very straight forward. I'm so happy cause I can now listen to music that's on my iPhone in my car. I recommend this product for anyone that doesnt have an auxiliary connection in the front panel of their car radio. Sonic, thank you so much for your great service and fast shipping. This product is just amazing.

This is perect. I was looking for a way to hook up my Sirius radio directly to the factory headunit and this was the only way to do it. After many phone calls and several stops at audio stores I found this site. THE PRICE WAS AMAZING. The local stores wanted over $125 for this same product. Now that I have my work truck (Silverado) I just wish it wasn't on back order so I could get one for my Chevy Avalanche.
