Updating MMI basic

Morning,
A friend has bought a 2006 A6 and has emailed me to ask if I know how to update the MMI Basic satnav. I don't know much about satnav units so thought it best to ask here. Can updated be downloaded legitimitely or via bittorrent sites etc?
cheers

Where did you find the navigation update mate? I think now that the MMI basic is the RNS-D unit. I don't know if there is any way to update it though. Most people seem to pay a lot of money to upgrade to the RNS-E instead.
 
that link doesn't work mate.

I thought MMI basic was RNS-D but don't know what MMI high is. RNS-E perhaps?
