Re: (Enfig Motorsport)
the new RNS-E is a DVD-based navigation radio that has a similar user interface as the MMI system found on the new A6 & A8..
the RNS-E is availble in the US in the B7-A4, the new A3, and the Allroad (which is based on the C5-A6).. the unit for the B7-A4 can be easily install in a B6-A4 and the unit for the Allroad can be installed in a C5-A6, and older Allroads or even an B5-A4 (with a little work)..
the RNS-E is not compatible with CD-changers, TV-tuners, etc for the older radios or CD-based Nav units.. therefore in most cases the existing AUX-IN modules and iPod adapters that interface with the CD-changer connection do not work with the new RNS-E..
there are different units for the US and Europe.. both systems can be installed in the US, but there are some differences.. most notably satellite radio capability, the US units are fully satellite radio capable -- there is no satellite radio in Europe.. the european system has been out longer and there is an ICE>link available for the EU unit, it is unconfirmed if it works for the US unit..
for details on part numbers, installs, features, etc check out the new forum dedicated to the RNS-E
