All four of my CDs in the Prius NAV unit are MP3s... There are about 20 folders in each CD for each individual album... the problem I am encountering is when I select folders, the display lists one screen full of folders but I am unable to scroll thru the folder lists. There is a scroll bar on the right of the display but the "buttons" are grayed out.
Is your car moving while you're trying to scroll thru the folder lists? In their infinite wisdom (and ignoring the possibility that a passenger is trying to find something), many of the "choice" options are locked out to keep the driver from distracting him/her self with the screen when they should be paying attention to the road.
will try that... the dumb part is the folder buttons on the first screenshot are still available for use... I can scroll thru the folders one by one which would be even more time intensive and distracting....
