Hey all, current got a 2018 audi a6 Quattro with software version RMC_EU_P16342. To be honest, car have decent spec but this software is real let down. Nav SD version is also 2017. Can anyone advise how I can upgrade? Ideally I want to use apple CarPlay and have decent upgraded .maps. Don’t want to start retro fitting screens etc. I have a couple of videos on YouTube about purchasing sd card and downloading another version but just to make sure I am doing the right thing. That’s why thought I should ask u guys 👍🏻. Advice welcome please, thanks
