Hello, I have had the following problem: I have had a V40 phase 1 with underground radio reception. GEHABT because it is now no longer underground but completely finito. I already looked through and read in the search function all the topics that there is about the roof antenna and the socket (which as is well known gladly gives up the spirit). I start with it that the screwing was so strongly corroded that the counter nut could not be solved. After several ugly turns (sock turned up with) a brittle rubber ring of the roof top and antenna closed off. Since the square upper piece of the antenna by the “hole” of the roof fit after I then carefully ripped off the antenna foot including antenna rod started the problems. Socket removed, how can it be solved… cable…. hhhmmm why are there three cables at the old but at my new antenna only two? when the connection of the old socket already a small “puff” as if a fuse flew out of it was also found for the antenna and why did not have found the fun of it.
