On my 2006 Passat I had a problem with bad reception on the radio. After alot of troubleshooting it turns out the wire to the connector on back of the radio was weakened and causing the static. I bought a few of theses Fakra connectors but am not having much luck with them and my cable wire is getting shorter. I am thinking about just replacing the cable with one that has connectors already on them.I have the rear window type antenna. I know the cable goes from back of the radio to the signal booster in the back window and I assume it runs through the pillars and the headliner. Is this correct? I am guessing that the cable is secured and you just can't pull it through using the old one. Is the cable one piece or is there a connector at some point? Any help or insight would be greatly appreciated.
