Install CNEUNT 2011.30 as the full MapSource version and choose the map tiles you want in your "gmapsupp.img" file while keeping the size below 2 GiB. That way you can choose exactly what you want.
Use a patched version of MapSource since MapID >= 2200.
Alternatively you can download one of the pre-built regional sets from [Only registered and activated users can see links. ].
