With the shutdown of AT&T's 3G service eminent, I've been thinking about options to keep out old MMI 3G+ systems connected to the interwebz, mostly for the Google Earth map style (which still works in our '14 A4) and the occasional on-line destination search.
In the U.S. market, the embedded phone module that provisions the 3G connection is the Cinterion AH6A-US (inside VAG PN 8T0051431):

Current Cinterion LTE devices appear to have a similar form factor, but different electrical connectivity (PDF HERE). I haven't actually opened a U.S. PPIS UMTS phone module (post T-Mobile) to see what the Cinterion device looks like.
Then there would be the problem of getting the old QNX system to work with the device, if the device connectivity problem can be solved within the MMI main unit footprint.
External data connection solutions have been around for a long time; I summarized some of these last year HERE. One of these may be project this summer (assuming we hold onto our A4q for a while longer).
Anyone else out there thinking about MMI3G+ mobile data post 3G ? --g
