Metra Electronics 40-VW12 Factory Antenna Adapter to Aftermarket Radio Adapter for Select 1988-2005 Audi/BMW/Mercedes/VW Vehicles (VWAB)

I upgraded the single din radio head unit in my W210 Mercedes wagon with a Sony model, and when I bought the wiring harness, someone recommended I pick this up to as the antenna would not plug into my new radio otherwise. This did the trick, was inexpensive and installed easily when I was switching the head unit over, works perfectly! Even though I do not listen to the radio all that much, I would have regretted putting it all back together without the antenna hooked up. No wires needed to be cut, on any of it. Awesome.

Most online forums state it is not possible to upgrade or install an aftermarket stereo into my automobile due the factory Bose system containing fiber optic cables. After extensive research and connector mapping, I determined it is entirely possible, but I needed an antenna adapter to finish the stereo upgrade for my 2003 Mercedes CLK430. The vehicle's antenna connector fits very tight onto the adapter, which is something I really like. It essentially eliminates the possibility of the cable popping off during the final radio installation. It works great and I'd recommend this for anyone installing an aftermarket stereo into an applicable European car.

installed this to adapt a Boss radio to my original antenna, works perfectly

The last one I bought was so expensive this is perfect. It works!

Was just what I need to put a mediocre car stereo in my mediocre VW Bug.

I used this on my 2006 Sprinter - works great. firm snap fit makes it unlikely that it will come apart after installation. If replacing the radio on a sprinter, you'll also want the Metra 70-9401 adapter.

Worked perfectly to adapt the Porsche antenna plug to a standard universal type antenna plug

Fits my '96 W210 and my Sony head unit perfectly. Great reception.

Works great for a Aftermarket radio in my 1999 mercedes e300td

Used it for my daughter's new stereo in her 17 year old VW Beetle. Easy to accurately find the part and fit perfectly.

Very straight forward, works as intended.

A cheap and effective way to adapt your import car antenna to an aftermarket stereo. I used it on a 96 Mercedes.

Easily adapted my 2011 Smart ForTwo antenna for an aftermarket JVC head unit. Between the SiriusXM Vehicle Tuner and the external bluetooth microphone I really didn't want another cable back there and this did the job.
