MrWright Posted September 21, 2023 Share Posted September 21, 2023 Hi there I am new here and recently bought a 2012 Audi A4 B8.5 Avant Black Edition. The cars had a lot of work done which I’ve taken care of myself. One thing I’m unsure on is the radio system. I’m unsure wether it has or had nav? There is a slot for an SD card but is that just for media? There is also a button on the steering wheel stating “NAV” but it flashes up saying button not used? I’ve also seen a few YouTube videos on the upgrade for apple car play etc with a junction box that sits between the radio module. Has anyone had any experience with these? Any help would be appreciated and thanks in advance. Quote Link to comment Share on other sites More sharing options...
