Hi all looling forward to being on the forum I've just brought myself a audi a5 sline 1.8tfsi 2015 and was just wondering how would I go about updating the navigation as it seems very out of date is it just audi who do it? Also has anyone had this done as wonder how expensive it might be? The other issue I've heard about the audi app is that worth subscribing? Many thanks Kev
