The Mercedes-Benz C-class head device (W204) Comand has several interesting features in Reggae mode. For example, if the name of the song does not fit completely on the screen, then you can click on the "grid" and a window with the full name of the song appears on the screen. Repressing the "grid" will clear the window. Also, if you listen to recorded songs or radio, know the file number in the folder or the number of the desired radio station, you can press the asterisk and enter the number to switch to the song or the wave.
