@Bavareze: As you noticed, the basemap only shows major roads and no other detail. This is because these maps are used for zoomed out views of the world and do not require such information. The detail maps (CN North America) sit atop this map.


Get the detail maps for Asia from your favorite site (Noeman.org for example), load them onto a SD card as described in the 200W tutorial Catymag linked for you and have fun.
