have a question about Peripheral Model PXDP3, i've read that only 25 listings of the playlist, artist ,etc are displayed on the nav. system.---something to do with the limitation of the nav itself---. what i like to know is 1. is that true? or is it possible to call up more than 25? and 2. is it worth it? i already have the gen3 lockpick---works great!!! i would really like other suggestions if there is something better out there.
