I agree with ILUVMILS. In addition to what he is saying, I am in Wisconsin, only about 2.5 hours away from the original poster (2 hours by MB
), and we don't have complaints of this here, or at least no one complaining of it. Have the software version checked and updated, it can fix lots of seemingly unrelated problems, and you can also pick up a few extra features if your current software version is quite old.
ps a few weeks ago we also received from MB a "diagnosis disc" for the comand unit, but I am unsure if this would be helpful in diagnosing the problem or not. If the SW version is the newest version, I would lean towards a new comand unit. Hopefully you are under warranty.
