1) Get a 32 Gig SD memory card.
2) Go to My Audi site,
https://www.myaudi.com Log in.
3) Click on the “Audi connect services” icon (below the car).
4) On the services tab, click the right arrow to scroll to “Map update.” Click on it.
5) You can choose “Complete package” or “Individual country.” Your choice. I chose complete package.
6) Put you SD card in your computer. Alternately, you can load the map files to your hard drive. Click on “prepare package” at the bottom.
7) This will download a file called “downloader” with a bunch of numbers after the word.
8) You need the latest version of Java. It will prompt you if needed.
9) On the Mac, I needed to go into my security settings to allow the downloader file to open.
10) It will open with a Java screen, followed by a Download client window that says “my Audi.” It asks you to choose a folder location for the files. Pick a location on your hard drive or SD card and click to go.
11) The download starts and is tracked in the Download client window. The size of the files is 10.6 gig. It took about 2 hours to download on my computer.
12) Once the files are downloaded, transfer them to your SD card if you didn’t load them direct. There will be two files “0231001C.md5”, “metainfo2.txt” and two folders “Mib1” and Mib2”. All are needed.
13) Go to your car. You can do this while you are driving or stationary but the car must be on (not necessarily running but on). I did it in my garage.
14) Stick the SD card into the SD1 slot in your glove box.
15) In your MMI, go to Main menu>>Settings. Push the MMI scroll wheel to the left, it brings up a menu that says “MMI setup” and “System update.” Pick “System update.”
16) Pick SD1 (i.e. where you put your SD card) and press the MMI button to select.
17) The nav update will start and inform you of progress on the MMI screen. My update took about 20 minutes to load in my car.
