Does not fit my 2004 Audi A4 B6 as described. I still rated it as 5 star, looks quality box but had no chance to connect it due to my stereo had no CD changer port.

Installation is easy works perfectly! Just remember you have to slide one of the extra plugs off the harness in the box and replace it with the one from the wyness unit. Instructions don't tell you that.It's well worth the price.

Wiring options did not match up when I pulled the unit. I've replaced car radios before but the included instructions were not helpful for a novice. I could see where I was supposed to plug it in but the plugs didn't match. I returned it.

Worked, fit perfectly.

Installed on my 2001 Audi Symphony system, the left front speaker emits severe add-on noise when playing music. Had to return it.

First thing first. Mine didn't come with the iPhone port. That's fine for me, because I don't have an iPhone, but keep that in mind.Works on my 2006 Audi A3 with the Symphony 1 stereo.Installation is simple. Use some stereo keys to remove the stereo. On the back of your stereo there's a brown connector, then two black connectors. (I think it's black, brown, black) The thinnest black connector is the one we will play with. Unplug it, and make sure it plugs into the red adapter that came with the Bluetooth device. Does it fit? Great. If not, try the other black connector. On the other end of the red adapter are three connectors (look at the blue one in the product pictures) that are snapped together. Yellow, green, and blue. Between the green and blue connectors, on the wire side, is a little tab. Push it to the green side, and slide the blue connector up. Once that has been disconnected, take the blue connector that is connected to the Bluetooth and slide it next to the green one. You're almost done. Plug the yellow, blue, green connector into the stereo, where the black connector was. Now find a screw on the back of the stereo that is connected to metal. Unscrew it and screw the ground wire (thin black wire with a loop end) back in, attached to the screw.If using the mic, you'll have to find a way to feed it to wherever you want to mount it. Then carefully slide the stereo back in place, until it clicks.Turn on the stereo, pair your phone, and enjoy.In my case, the music streams fine. The calls are a little quiet, but I rarely talk on the phone, so it's not a big deal. My car has the controls on the wheel, but never had the nav system or Bluetooth. That means that only the volume and prev/next rollers work. I'm still looking to see if there's a way to program the other buttons.Protip: More important than the year and model of the car, is the model of stereo. If your stereo matches the listing, it will probably work.Enjoy.

This is a great device to bring an older car into the 21st century. I can control my music wirelessly through Bluetooth connection. Installation was a little tricky as instructions were not crystal clear, but I was able to figure it out. This was a good purchase because other devices cost much more than this device. Take your time and bundle all the wires up nicely!

Installed in a 2000 Audi TT Quattro. This could have been a five start rating. The Bluetooth works great I haven't used the mic or the auxiliary port yet (I have an iPhone 7). The only issue I had was using the lightning port charger my phone tells me the the accessory is not supported. Other than that it's a great product.
