I installed this and the cam is telling me that there are Lens updates available when I switch it on,but the lens firmware on the owners area is not new..
You will need to perform the firmware install with each lens. When downloading the firmware from the Leica website, you will find only the camera firmware, but it will contain the lens firmware as well. After you have updated the camera firmware, and you attach a new lens, it will show you that the lens firmware will require updating. Simply repeat the install process (pressing the joystick when turning the camera on) with each new lens and you should be set.
