Problem solved with radio reception.

as well all that I have so buy an adapter previously also had a very poor radio reception in my VW Golf 4, Bj. 2002. Besides the fact that VW also the ignition plus and the constant plus easily reversed, you have to know first and as long annoyed that, just all programming is every time the key is pulled away until you know it, also comes yet this fun with the phantom power. So I have so bought an adapter, the antenna connector connected thereto and brought to power by a blue and white cable that supplies according to Internet manual in case of a retractable antenna with this power, once you reinsteckt the key. Since I do not have such an antenna, I disconnected and there connected the cable from the adapter, and lo and behold, crystal-clear reception of stations that I did not even know before ^^
