Customer Ratings & Reviews

This made the install simple and worked fine on 2009 clk350. Didn’t have to use the speaker wires as mine had a MOST fiber amp. Just purchased a $100 MOST adapter from the web and the factory speakers and amp worked great. It is prewired for the steering wheel control harness from Axxess which made the install of that harness very easy.

This harness works very well. I did not list the user of steering wheel controls

Item came as described. I'm sure its going to fit and work well. Just really need to get my stereo installed already GeekSquad..... I've got $2,000++ sitting in my living room since December 1st.....

Love it ,very good product and excellent stuff,thanks a lot .

Excellent service and and ease of use. Great job. Thanks

This product came right on time and worked perfectly. This is the only way to go in my opinion. Makes a professional job of it

Very important to have if your vehicle is a Mercedes sprinter

It made the installation easy and professional. I recommend it

This was purchased with the Pioneer stereo AVIC-8201NEX and works great. Price was competitive.

Interfaces well with radio and car. Nice to be able todo that

Just what I needed to finish the install of my new radio

This adapter works well with my Pioneer 8201 NEX system.

Exactly what i needed for my stereo. Amazon price match really helped.

Excellent service. Wonderful product. After the installation the serviceman sat in my car with me and showed me how to use the system.

This part was necessary for the operation of the unit

So this is the second time best buy installed the interface and it still wont save my radio presets. Dont know why interface says its compatible with my 2008 benz but it is not. Please help!

As other reviewers have noted I wasted several hours of my life in ordering two of these harnesses and in the end both failed to deliver what they state they could do. I have a 2010 Mercedes Benz GLK-350 non-premium but don't think that matters as all other cars listed I am not confident this product is for my car despite many sites stating otherwise. Sad, in the end lost all functionality of my steering wheel controls for a radio that now feels like a very expensive Bluetooth speaker.
