Review on 🔌 Metra Electronics 40-VW12 Factory Antenna Adapter: Suitable for 1988-2005 Audi/BMW/Mercedes/VW Vehicles (VWAB) by Andrew Carrao

Most internet forums claim it is not possible to upgrade or fit a stereo system in my car as a factory Bose system contains fiber optic cables. After extensive research and connector comparisons I thought it was entirely possible, but I needed an antenna adapter to complete a stereo upgrade for my 2003 Mercedes CLK430. The plug of the car antenna is very tight on the adapter, which I like very much. This virtually eliminates the possibility of disconnecting the cable during final installation of the radio. It works great and I would recommend it to anyone installing an aftermarket stereo in a qualifying European car.
