My command system turns on for about 45 sec , then turns off for 10 sec (repeating) over and over again.
I called mercedes and they suggested I bring it in for a diagnosis, per hour is $125.00. He mentioned a programming update may be needed. I bought he truck used and no warranty, I was wondering if there was a re-boot sequence for the command. Or simply would disconnecting the battery reset it.

There isn't a reboot sequence and most updates will fix alot of the bugs. I had it done on mine, thankfully mine is still under warranty.
