So, I went to wash the wife's car yesterday, and (as always) struggled with unscrewing the roof antenna from its base. This time, however, the thing broke.
Now I'm thinking, is this something I can replace myself? How do I even get the broken antenna base off the roof (it must be fastened from/to the inside)?
FYI, the image below shows the location of the antenna base between the windshield and roof window.
