Default Original Samsung Multimedia dock for NoteII

Hello,
i've got the Original Samsung Multimedia dock for note II and i notice something strange....when the phone i connected to the dock often losts the signal and i'm not able to make or receive calls...and obviously i'm not able to navigate...i can navigate only with wi-fi

When i disconnect the phone the signal returns
is there someone else with this problem?
