Alpine cda-7897

wonder if anybody has had a chance to try the new alpines with the
fantomface. I was just toyin around with one down at cartoys in houston
texas and was disappointed. the face would black out if it was left idle for
about 5-10 secs. also, i had problems with it going thru folders in my mp3
cd. the folder up and down buttons didnt work, and i had to skip through all
of the tracks in folder to get to the next. it may just be a problem with
the display model, but i wanted to see if anybody else notices any problems
with it.
