OK, there should be a way to do this right?

Since the RNS-E can display the song text from an mp3 file via and SD card, why can't there be a way for the text to be displayed from an ipod interface. I know ipod interfaces use the cd changer connection to plug into the unit, but can an interface be created that used the same SD card interface. WE would then have the RNS-E doing the mp3 decoding and the ipod would just be acting like a hard drive.

a USB interface would be awesome.

You see there are several issues which prevent this approach. There is no interface into the RNS-E which would support a communication protocol which could be used to transfer text.

Ok, now you will say wait a minute, what about the SAT receiver? True, but this is an option for the US units only (which limits the number of possible customers = less interest on the developer side).

Even assuming you target only the US customers, you would need to develop a custom IC which talks over the Audi Infotainment CAN protocol and emulates a SAT receiver. You would loose the SAT receiver functionality unless you add something which would allow to connect the OEM SAT receiver to your device and then trick the RNS-E to allow switching between both.

The more likely option is the following: The new A6/A8 MMI systems allow more than one device to talk over MOST (similar to CAN but higher speed whcih allows even audio). The MMI systems even support two CD changers plus a TV tuner. And it's available in Europe and North America which makes the audience much larger. I also think that eventually Audi will support features of today's MMI in the A4 (probably B8) and maybe even A3. Together with the announced support for BT audio devices in the far future, this will provide enough links into the OEM systems to develop custom devices.

Dension is rumored to develop the IceLink MMI for the A6/A8 which would be the first 3rd party interface available. There is also a group in Germany trying to develop a Linux PC based USB interface for MP3 player which uses the TV interface into the RNS-D. It's pretty quite right now in that area and issues not solved are missing RNS-E support and missing video in motion. Besides the price which is aiming at 1k Euro for the MP3 player (not including any storage).

What does this mean for today? I think unless you are a developer who can create his own little programmable IC, changes are close to zero that we will see and text enabled, fully integrated, external audio device for the RNS-E.

I would love to be wrong but I wouldn't bet any money right now on this...

Back in time I tought about connecting USB HDD to RNS-E via SD-USB converter. I never moved to actual tests but in theory it's very possible.

In that case HDD would work as a big SD card (20Gb for example) of course only if RNS-E would allow to read such a big SD (we know that it's capable of reading much more than is stated in specs).

So you could open RNS-E and run wires from SD reader to the back through SD-USB converter. This could work with USB HDD, but I'm not sure if iPod would act like a regular HDD. It could be more to it.

An Ipod can act as a USB harddrive, but when you put songs on it they their names are changed to 4 or 5 characters and they aren't sorted in anyway. So if you read the ID3 info from the file you know what it is, but otherwise you just have a bunch of poorly named files in one of a handful of directories.

When Apple released the ipod nano they said that many car manufactures were doing to have OEM ipod interfaces. If you look at this page http://www.apple.com/ipod/ipodyourcar/ Audi is listed as coming soon.

That's if you use Itunes to load the drive. If you treat the drive as a regular USB drive and load the songs just like you would with your SD cards, there will be no issues.

that is true, but then it wont work like an ipod.. so you might as well just get a USB harddrive..
