So i recently bought a 2009 Audi A4 and was hoping it would come with navi but it didn't. So I want to get navi but im a first time audi owner and have no idea on where to get my information on this kind of things. So i was hoping that someone from this forum can possibly enlighten me on how to get navi for my 09 audi a4 that doesn't have it.
