View Full Version : SD for MMI in 2007 A3...

Two questions regarding SD chips for the Audi Navigation Plus MMI in a 2007 A3:

1. What is the largest capacity it will handle?

2. Will an SDHC chip work?

I'm looking at the Patriot 8GB Secure Digital High-Capacity(SDHC) Flash Card Model PSF8GSDHC4 from here. (http://www.newegg.com/Product/Product.aspx?Item=N82E16820220217)

Thanks for any info...

Not sure if it's been confirmed, but I doubt the HC cards will work. A number of folks are running 4GB cards. Whatever you purchase, I'd recommend Ultra II - the higher I/O speed may or may not help when installed in the deck, but it'll definitely be a time saver as you transfer the data files from your computer to the SD card.

First, since you've got an A3 you don't have an MMI system (I know it says "MMI" when you turn it on but that doesn't mean it uses MMI DVD's - it doesn't - or is a fibre optic system like the MMI in the A6, A8, Q7 - it isn't), that's a crazy piece of marketing by some marketing buffoon at Audi.

The RNS-E (your sat nav) does NOT work with SDHC cards, only SD cards. Buying SDHC will be a waste of $$$.

The largest SD cards you can get is 4GB. But don't make the mistake of thinking that's the only limit .... you are limited to:

- 512 "objects" per SD card (MP3 files + M3U files + folders + sub-folders).
- file paths of 64 characters.
- filenames without "special" characters like "!".
- MP3 files without DRM.

I use 4GB SD cards from a variety of suppliers online and off eBay. Like VroomVroom I always buy the highest speed cards, not only do they download faster but I had problems with standard speed cards on my first RNS-E.

Thanks for setting me straight about "MMI" and for the extra info on the SD cards...
