Hi there

You will need to obtain the latest updates direct from Mercedes.

Let me know if that helps...

Sorry but I know That, I was looking for possible faults that would cause the problem I stated. I assume many gps systems that exhibit the problem I described have the same fault.

A glitch in the firmware would cause this fault. The only way to rectify this is to install updated firmware.
