What are you talking about? The CD player? You can reset the head unit in the engineering menu for the HU. Or maybe eject and reload the discs.

Hold down the END-CALL + # + 1 buttons simultaneously until the engineer mode menu is displayed. You'll have to go through the menus to find the head unit reset function. It may show as MOST restart or reset. It's been a while since I accessed it. If I remember tomorrow, I will try to find it.

Another way to reset or restart the COMAND unit is using a bi-directional scan tool. In this link, I am using a LAUNCH Creader Elite BENZ scan tool.
