Right, clever people... I have a 2013 A3 and the maps on it are **** - there’s roundabouts on there that were changed into a road 13 years ago!? The software is MSTD_EU_AU_P3151 and navigation is 8V0919866A 0021 ECE 2013. I literally have no idea what any of it means and didn’t know if anyone can advise what I need to do or download to get the correct software. I contacted Audi who quoted me £600 for the pleasure (which I begrudge paying on my sh!tty NHS wages) so thought I’d give it a go myself as I've seen lots of posts saying it is doable, I just don’t know where to start!
