Question Details

Hi, I got a new speedometer for my M B, but it doesn't communicate with the car, so I don't know the speed while I'm driving.

If your old odometer was turning on but was not working (partially), my guess is that the new used unit is defective. Those units don't need programing. Well other than miles. :)

I would check the connetor on the back of the cluster. Sometimes it may seem that it has been pushed in, locked in place but it is not.
