Same issue here too, especially in the morning in cool/dew areas. I'm thinking my issue could be that the rubber between the antenna and the roof looks worn, and it's possible I might have a short in there? I usually start with static for a few minutes and then clears up as I drive, first thing in the morning only. Beyond that, reception does seem weaker in more wooded areas than my previous car, but that did have an extending antenna. My old car was also a Ford-derived vehicle.
The FM antenna is located in the top left section of the rear window. Its the top four lines that look like part of the rear defroster. The shark fin is decoration unless you have factory nav, then it houses the gps antenna. The FM amplifier is located behind the drivers side c-pillar right by the antenna.<p>Yes a metallic based window tint could mess with your radio reception.<br>For most Seattle based radio stations the coverage in Olympia is already between "local" and "distant".<p>Example Coverage Map<br><A HREF="http://www.radio-locator.com/cgi-bin/pat?call=KUOW&service=FM&status=L&hours=U" TARGET="_blank">http://www.radio-locator.com/c...urs=U</A>
