Wanted to update the maps in my car’s navigation system. To Audi’s credit they provide twice-yearly upgrades via a variety of methods, some free. (Sadly they don’t seem to have any way to update the MMI firmware though). The map updates are badly documented, so here’s the details.
First, the easy options that cost money. You can pay the dealer to do it. Or you can pay for the Audi Connect service (the cellular data for your car) and updates come over the air.
Now the free manual option. Discussed here, also see this video. It’s not hard or scary, the only real nuisance is their Java download program. Detailed walkthrough:
Downloading update
- Log in to myAudi.
- Click the “Audi connect services” button. I had a lot of trouble with their SSO redirects, maybe related to my ad blockers and privacy stuff.
- On the Audi Connect website go to Services / Map Update and select “Complete Package”, then click the “Prepare Package” button.
- Download the map update! Ha ha just kidding. Download a tiny JNLP file for Java Web Start to run a download program that Audi requires you use.
- Run the JNLP program. I managed finally by enabling it in the Java control panel (Security / Enable Java content for browser and Web Start applications) and then running “javaws foo.jnlp” from a command line. Perhaps there’s an easier way.
- Wait for the download. The full US maps were about 11GB.
- The download program creates four files. Two small files: one named metainfo2.txt and one named randomhexstring.md5. And two directories with the data: Mib1 and Mib2. Apparently all 4 are necessary for an update.
- Copy the 4 to the root directory of a FAT32 system on an SD card. (A USB drive will work as well.)
Apr 29, 2016 Unable to download offline maps in windows 10 I recently upgraded to windows 10 and now I'm unable to download offline maps. Updates are fine. That means internet connection is ok. But when trying to download maps it is loading and nothing happens. Anyone know a solution to this. AUDI A1 MMI 3G+ PLUS SW 0942 + 2019 MAPS FULL PACKAGE.

Installing update
Free Java Download Windows 10
Requirements CPU RAM GPU Storage OS Notes Minimum Intel Core i3-3210 / AMD A8-7600 APU or equivalent 4 GB (2GB free) Integrated: Intel HD Graphics 4000 (Ivy Bridge) or AMD Radeon R5 series (Kaveri line) with OpenGL 4.4 1 Discrete: Nvidia GeForce 400 Series or AMD Radeon HD 7000 series with OpenGL 4.4 180 MB for program data, though worlds can drastically increase this amount.
- Go to the car and put the SD card in one of the slots for the MMI. (I used SD2).
- Turn the MMI on. (I do this by turning the radio on, not the ignition).
- Go to Settings / System Maintenance / Version info to check the versions of things on your system already. This shows the MMI software version (0694 for me) and some basic navigation database info; you have to navigate to the Navigation database submenu to see all the databases you have. My car had about 20 2016/2017 databases for North America, plus a single 2017/2018 for USA, Region 4 (California, where I live). That was an OTA update I got right after buying the car.
- Go to Audi Connect and select “Software update”. Select the source you plugged in (SD2 for me) and it begins. It takes awhile, about 30 minutes for me.
- Leave the car and close the door. Lights will turn off but the MMI will continue to be running with the screen lit and updating. Eventually the screen will close and it seems to keep updating. Hopefully none of this drains the battery too much. The update is automatic and requires no extra input
- Once it finishes you may have to enter a single click to acknowledge the update.
- Go back to Version info to check the version numbers. Now all my car’s maps are labelled “2018”. Success!
Of course I’m curious about the contents of the update files but couldn’t find a lot of info. Mib1 has a directory named “Eggnog” and Mib2 has “Truffles”; internal product names? Mib1’s datafiles seem to be named “.psf” and Linux guesses some (but not all) are FoxPro FPT files, which seems plausible. Mib2 is mostly compressed data I couldn’t figure out, which some small SQLite tables without much interesting it. Probably all proprietary data, of course, and if they’re smart it’s encrypted too to prevent casual snoops like me from lifting all the data out.
Shame Audi doesn’t also let you upgrade MMI firmware. Mine has a bug where it’s limited to indexing 10,000 music files. Admittedly that’s a lot of music, but it’s a nuisance if you just want to copy all the music you own into the car. Static array sizes: not even once!
What is JNLP?
JNLP refers to three things, both associated with Java. First, it can refer to the JNLP-extension format, which is an XML file format. Second, it can refer to the Java Network Launching Protocol itself, which is used in the creation and operation of JNLP-format files. This protocol is what provides the guidelines on how a JNLP or Web Start application should be executed. Third, it can refer to a JNLP client. While there are several of these available, by far the most common is Java Web Start. If he has this application, a user can use the Java Network Launching Protocol on his computer.
Java Web Start can be understood as the mechanism by which JNLP files are launched on a computer that has requested them from the Web. It parses JNLP files, checks what resources the files require and requests them, then launches the application once all the necessary resources come together. As such, one may think of it as the equivalent of a web browser for HTML files—it is supposed to be used with Java applications that are served from the Internet.
