Audi Navigation Plus
Audi Navigation Plus is an in-car media and navigation system developed by Audi. Unlike the Audi Multi Media Interface, it can not control climate, convenience, suspension or engine settings. Audi Navigation Plus units were available mostly as an optional equipment instead of standard stereo systems.

Car fitment
Originally equipped
Audi Navigation Plus was available in number of cars, including non-Audi models. Since Audi, SEAT and Lamborghini are owned by Volkswagen Group, RNS-E devices can be found in SEAT Exeo (optional equipment)[12] and the Lamborghini Gallardo[13](standard equipment).
RNS-E 2010 was remodeled to fit in Audi R8, but internally it's the same device.
Retrofited
Many car owners decided to retrofit one of the Audi Navigation Plus units in cars that were not equipped with RNS, or even not supported by the manufacturer. Since Audi cars share most of their components, it was possible to install RNS-D or RNS-E. In some cases, additional modules were needed to achieve full functionality.
