Very well pleased. Easy to install, took care of the screaming noise.It really helps boost the output,before I ran the volume around 18 to 20,now it is 9 to 12.

Installed for a month. Plug and play is true. Sounded great when I forst installed it but now have trouble with right rear speaker. Hope it's not the unit and just a bad speaker.

Just like it says... plug and play my sirius radio never sounded soooo goood one of the best thing i have bought

Installation instructions are straight forward and easy to follow. I bought this for my Delphi 2 XM Radio and thought all was well until I found the radio was only playing out of one front and one rear speaker. I finally found that the auxiliary plug from the bike did not match up well with the plug from the interface. You had to pull the auxiliary plug out about 1/16 of an inch for all four speakers to play. The manufactures solution was for me to find a spacer and use it to hold the plug in the correct position, or return the product to Wingstuff. He stated they have only had this problem with a few bikes and that if he sent me 10 replacements none of them would work with my auxiliary plug, which is the stock plug on my 2005 GL1800. I ask if he had a spacer and he said no. If you purchase, hope you don't have the same stock plug I have on my bike.

The hardest part of the install was routing the wires to the radio location. The kit itself is plug and play, and performs perfectly. I like that it leaves the Aux input accessable so the sat radio can be unplugged and say an iPod or something else plugged in in it's place. You could even just put an off the shelf "Y" adapter on the Aux Input if you wanted to. Love listening to the Blues on those long rides.

Completely eliminates the alternator whine from satellite radio system. Highly recommend you include this as part of the original install of your radio. You will save yourself time and effort if you do this right from the start. I haven't met anyone yet who didn't have to go back in and install this. Great product.

I installed this product several months ago. It did indeed provide power to the DELPHI Roady XT radio and installation was straight forward. I connected the accessory wire instead of using the FM modulator on the XM radio and was rewarded with a significant INCREASE in ignition and alternator noise. The device created a 5.8 volt bias on the input pin and I got some output even when the XM radio was disconnected. If you drive slow and never rev your engine it will be fine otherwise there will be a very fine high pitched whine as a background component in the sound particularly when using headsets in the helmet. I have since removed the XM radio and still use the audio cable for a connection to a Garmin Zumo. I maximize the output from the Zumo and keep the stereo volume lower to maximize the sound to noise ratio and it works ok.

Just installed a week ago, well worth the money, my sat. radio sounded like crap dealer installed, ( Radio Shop). now I broke down to spent the money on this kit and it sounds better than the stock FM radio, thats the results I was looking for. Great product, easy to install, must have to run SAT. radio right. Thank you

Just installed this product. Plug and play is the truth. And it did get rid of my alternater wine great product thank-you
