Thanks all for the updates so far (plus thanks to Jochen offline!).

I will be putting my Mk4 dvd unit into the RR this weekend and then updating bits as needed using Navcoder!

Just one question I've seen muted around on all sorts of forums is what OS update to go for. I took one off here that's V31 with a RR splash screen - is that sufficient for me? Then I found a website here (BMW MK4 SAT NAV DVD DISC HIGH ROAD MAP 2010 NAVIGATION UPDATE) that's showing a v32.2 as being the latest software.

So couple q's:

What one gives day/night mode?
What one allows 7 digit postcode?
What one allows speed camera POI's?

Cheers!
