I have a 2008 C300 with Command system, when I put the key in the ignition, the screen flickers on and off exactly 10 times then shuts off. Althoght the screen is dead I can still have control of all the function, changing CDs, raising volume, music still plays, etc. I have researched the forums and and pulled out fuses 11, 17 and 26, no help. I removed the head unit and checked for loose wires. Please Help

 

i would try a software flash of the headunit first. should be under warranty. 4 years 50K miles
