According to Sensis website v13 should be coming in November (although has been delayed monthly since June!). It's already available in a number of handheld PDAs (eg Tom tom) and it seems there are still errors and omissions galore as per Sensis style.
Have any Aussie users played with the idea of adding the Speed Camera locations onto their maps? I noticed the UK guys have done this and there is even a site that explains how to (including Videos of how to!!):

And the aussie Camera locations (along with lots of other POI) can be found here:
www.ozpoi.com
I believe the files on above website can be converted to something compatible for BMWs with POIConverter.
Anyone given it a go? I'd try but I'm a very pressed for time at the moment.
