you can get the title/tag to display by:
Press the <MENU> button and use arrows Right & Left of volume control to scroll through the menu items. When you get to MP3TEXT, if it isn't set to ID3, use volume knob to select ID3 or FILENAME.
for ID3 tags: if you get only two characters preceeded by a blank space and may be TT, TB, TC, TP, TN, TH, TW, TA, TD, TM, T', TF, TJ, TV, TI, TS, TL, T1, TR, T8, TQ, TG, TE, or TK. that's because the mp3 files' tags saved can not be read by the player.
see
Radio 10 & ID3 Tag display for further explanation.
