Thanks for info aekhong
There is no such thing as perfect map
CN EU is the best solution for all western EU countries, but for some central and some other countries, maps from local providers are much better
So, for myself I've made compilation:
CN EU 2011.10 + Adria Route 3.00 + SCG Route 2.20 + GPMapa 2009.4 + Atlas Czech 8.1 + Slovakia Roads v6 + NaviGuide Hungary 5.4
to get best coverage, even this is far away from perfect, but is much better than only CN EU
Best solution is to have all maps in MapSource, and to make yourself compilation of your choice
