I just received the official notification of 2011 map availability - BMW Navigation Map Updates Store

It still seems to be on a pair of single-layer discs for some reason.

I didn't purchase the 2010 map due to numerous posts here saying it had lots of problems compared with the 2009 version.

So, I'm wondering if anyone here bought the 2011 maps and can comment on their quality compared to 2009 and 2010?
