Hi hope someone out there can help me ,I’ve just bought a 2014 A3 and wondered is it possible to get the sat nav to work.The car has the MMI and is fitted with 2 sd slots and a dvd slot but it didn’t come with an sd card or dvd .So is there a relatively inexpensive way to get sat nav working or would I need to go through an Audi dealer.Ive seen sat nav sd cards and dvds for sale on eBay but would it be that simple.Thank you in advance of any help given.Paul
