To the best of my knowledge there is no such thing as the "European Chip", and even in Europe the TV picture is only visible until a speed of 3km/h or 2mph. In certain markets the hand brake has to be engaged for the TV picture to appear. You can see in the pictures that I've posted below from both the UK and German E60 owners manual that this is the case in both of those European countries.
The only way that I know of to see the TV picture while the car is in motion is to buy and install 3rd party modules. Five years ago I bought the oem BMW European TV tuner for my wife's E53 X5 along with a 3rd party video in motion module that plugged inline to the bus which allows the video to be displayed while the car is in motion. Dominic from TVandNav2Go.com posted in the following post that they have these modules for the E60/E90 and he feels that they would also work for the E70.
