I heard there was a newer version (8.21) software update for the H.K. radio, so I went to the HD website, downloaded it, burned a cd, put it in the radio and it updated without a problem. Everything seems to work fine. Now I want to know What the update consists of, or reason for it. I was told it enabled the artist/song info to be displayed from home burned cd's and mp3 files (it doesn't). I can't find any info. on HD site or HK. I have googled every thing I can think of with no results. Does anyone know where some info can be had on version 8.21? I had version 8.19.
