Looking at the new A5 Sportback here in Dublin. Unlike, the UK the MMI Navigation Plus does not come as standard. It's an option at €3.5K which is pretty expensive. There is no difference in screen sizes etc if you don't pick it. The Virtual cockpit is then another €500+ option which you can spec without the MMI plus system. Is the MMI Nav Plus a must-have option for those using it? I use Waze and Google Maps via carplay in my current E class saloon. I know you get the cool Google satellite maps in MMI plus, but is there anything there that would make the system a necessary option? You can actually buy it after you take delivery, it comes prepped as standard.
