If you have the red dot matrix display with check control (all those icons for oil, brakes, water, etc.) then you should be able to upgrade to the DIS by installing a new wiper switch (involves removing the steering wheel) and making some VAG-COM changes. The same way you can get cruise control on some models. Here's the original link:

The RNS-E will not display any of those information.
