Hi I m new to forum, I have a 2006 cls 320 sport. When I first got it the command unit worked but now it switches on and the Mercedes sign comes on the screen but after about 30 seconds the unit shuts down. I have noticed there is no illumination on the control butons of the unit when the lights are on. Edd

Usually a MOST fibre ring issue. Could be the fibre itself or another control unit within the ring. Could try reset MOST devices from their fuse or bypass devices to test for a difference.

do you have a Bluetooth system and are you playing with your phone when you get into the car.

Hi I have a Bluetooth phone but its not that. The unit only shows the Mercedes badge and name then shuts down, no radio, nav connects. I have checked all fuses and even dis-connected the battery but no good.

see if the dealership will do a free update to the comand, if not, same as an e class... upgrade the comand to new technology. check to see if your amp has power its the audio gateway in the trunk.
