I recently upgraded to an Alpine 9833 and I find that it does not show any characters for CD-text. Mp3 text works fine. I burn copies of most of my CDs and input text to see the names of the songs. The 9833 just shows a blank instead of the text. It shows "no text" if there really is no text but its just blank when there is. My older Alpine 9811 read the text just fine. I returned this head unit but the replacement has exactly the same problem. What is going on?
