Review on Xtenzi EU Vehicle Antenna Amplifier Adapter XTDIN12: Compatibly Designed for Select European Car Radio Models. by Roman Niko

Did exactly what it was supposed to do. I converted the factory antenna to the standard antenna without any problems. I wish the wire wasn't so long. The resonator already has a ton of wires, and adding those just makes it disorganized. It would be easy to just omit the wire and connect the two ends together, reducing manufacturing costs and resulting in a more compact solution.
