My 2006 CLK350 Command screen when turned on will only show MB logo and static sound. I had put a navigator DVD update in and it would not initialize and would not eject. To fix the problem I disconnected the battery for 60 minutes and when reconnected now I only get the MB logo with static and the logo does not go out as long as it is on. Is there a fix I can do without going to the dealer? There are no error codes. Thanks MBWorld
