Hi all I got a 2005 e53 this week. It has 2005 map DVD and is running 4/1-00

I believe v31 and v32 are identical apart from v32 reads dual layer DVDs.
My question is how can I tell if I'm on v31 or v 32 as both versions identify as 4/1-00


Also I am after a 2013 map disc with speed camera (I live in uk)

Do I need a custom version of v32. To give me day/night and turn camera location on/off. And can someone point me towards a link to dl the map and software (I would like to keep original flash screen)
