The RNS-E is using the MMI user interface but it is itself not a MMI system. Only the systems in the A6 C6, A8 D3 and Q7 are MMI systems. The 4B0 RNS-E is the right unit for an A6 C5.

I'm really confused as to the differences between RNS-E and MMI.

On the one side, the new A6 has replaced the previous model's RNS-E with the MMI which, together with the use of MMI in the high end A8, would suggest this is the newer, superior unit which will totally replace the RNS-E over time. Is this correct?

On the other hand, the latest B7 A4 still uses the RNS-E, although this was merely a facelift and not a totally new model which could explain it.

The MMI is obviously a superior unit to the RNS-E but what exactly does it do that the RNS-E doesn't? I'm just curious really.

The 4B0 035 192P will fit an A6 C5. Each navigation DVD contains the firmware and will automatically initiate an update if when you insert the DVD the first time (exception: cross region updates).

The upcoming A5 and 2008 A4 (based on the B8 platform) are rumored to get the MMI from the A6/A8/Q7.

It's easy to determine if a car has the MMI or the RNS-E: If the display, DVD drive and controls are all in the same location then it's an RNS-E. if the controls are seperate from the display and DVD drive then it's the MMI.

What is the real difference?


MMI just looks like a repackaged RNS-E. So thta the controls can be mounted in the console.

MMI is based on a fiber optic network of separate parts.

RNS-E is a single unit that operates over the wire CANbus.

The MMI screen displays many functions of the car (Entertainment, HVAC, etc).

The RNS-E screen only displays entertainment functions.
