here is a handy skin command (with guino's help...)
a single button to toggle though the HD Sub Channels
need someone to make a nice HD Radio specific skinCode:"SETVARBYCODE;HDCHAN;HDSUB||SETVARBYCODE;HDCOUNT;HDSUBCOUNT||EVAL;HDCHAN;1+(($HDCHAN$)%($HDCOUNT$))||HDSUB;$HDCHAN$"
maybe take the BMV2 as a base and make a new Radio_Player.skin and jpgs
just to show how to use HD Radio
