I had in my VW Golf IV a punk radio reception since I swapped the original radio to a radio accessories. I built a Phantomeinspeißung this because the antenna was no longer fed via the radio in accessories 12 volts. The reception is again optimal, as it should be. Installation Difficulty level: Easy
Installation Tip for beginners:
The blue wire must (or should) be connected to the ignition +. The rest merely stuck between radio and antenna.
