Audio Systems: 99 nissan centra radio, nissan centra, some stations

Question
Hello. I have a 99 nissan centra. A few days ago my radio start to act weird. It plays some stations fine but, most of the stations i get a strong static. My take on it - its got something to do with antenna. How do i take the radio out? Also, may be you have any suggestion on this matter? Any help will be greatly appreciated.

Answer
Missing info, Do you have the mast type anttena or the built in version?
Airel lead into the set could be loose or at the airel or , as has happened, a loose inline connector under the trim.
Radio removal requires the facia of the centre consol to be removed as the radio is screwed onto a frame behind it.
