I have a 2011 A5 and I'm curious if there's a way to upgrade the navigation software. There's several addresses I've put in that don't come up. I'm also wondering if there's any way to update the MMI 3G software in general. The stealership is saying there's no software updates unless I have an issue to correct and for updated navigation software its about $500. Any better ideas? My main concern is the navigation so if I cant get one for the rest of the system I'm fine with that.
