So I'm coming from a 2012 Audi A3 Black Edition Quattro 8P (last generation), and looking to upgrade to this year's equivalent-ish model, minus the Quattro. I currently have the Navigation Plus (RNS-E) system, which doesn't have full postcode search and has, frankly, always done my head in. The nav system itself is great, but the lack of full postcode is just infuriating. So first up, because it's a dealbreaker do we get 7 digit postcode search yet? Second... how worthwhile is the MMI Navigation Plus over the MMI Radio Plus? Is it worth the extra £1.5k? I can't work out the difference I'm particularly looking at this section when I click the tech pack info on the Tech Pack Advanced: "Detailed route information: map preview, choice of alternative routes, POIs, lane recommendations, motorway exits, detailed junction maps and more"... does that mean the regular navigation doesn't include those things?
