I have the BCD396XT and cannot seem to make the weather function work. Maybe I am reading the manual wrong or I am overlooking something. I can go to menu and then to WX scan and everything will work find but if I read the manual right I should be able to press the function button and then long press the WX/O button and this should start weather scan, but when I do this nothing happens. What am I doing wrong? Thanks for any input.
