Can anyone who owns the UMT+ tell me whether you can use the oppo iPAD app for the BD103 to navigate around stored music files on a USB stick or HDD connected to the player? I have seen that there is an MSB app for remote control of the DAC IV and UMT+,but that just seems to duplicate the functions of the remote control whereas I am interested in being able to navigate menus without the need to have a display attached to the player and think you can do this with a BD103.
