Am sure the actual map data is the same for pre/post facelift, I had 2012 and it:

Didn't have my street which has been here since 2003
Didn't have Bristol Audi at their new location (they moved in 2009)

2013 update had all of these...was it worth the £200...dunno really

I do (if I'm correct in my assumption) find it a little cheeky that you have to pay Audi to enable the nav & MMI updates on facelift C7...but figure they learned they were loosing monies on knock-off 'back-up' copies
