Other than using data on a SIM card and your MMI as a router I don’t think it provides any extra functionality. For the online Audi connect functions you need to subscribe to Audi connect after your initial 3 years and it’s like £17 a month. That gets you connect with weather, online traffic, google map overlay and a whole heap of crap you will probably not use ever. Mines coming up to 3 years so probably not get it as £17 a month is a rip off so CarPlay it is even though I’m not a huge fan.
