  3. What you need that is PlayList which is programmed one’s requirement. Further you can store audio files (mp3) in alphabetical order like A1, A2, A3,… B1, B2, B3 etc. All the songs will be played sequence-ally one-after another..

  4. This type of module fails after short time of usage. I purchased 3 such kits for my home use but all those started having problems mainly Failing to detect usb drives while the FM and Aux in functions remained Ok. I found that the Panel type modules have better longivity and all the connections to the board comes completed. Also the display is bigger with Time elapsed function. One has to only connec Power and Audio wires.

    • Comparatively this board is old but the new VIRE board available in the market can be operated without IR remote. However, the use of IR remote is much more convenient and can access the full functionality of the board.
