You can use in the future all activatible (existing code!) Low-Level-maps (e.g. from the newest release 970_7490, 971_7520...). Your device-NC 8.041 must be patched before (look at #19)
For the map-release 970/971 look here in #1: [Only registered and activated users can see links. ]
For your Africa-wish at the moment only the Africa_965_7252 (from the release before).
Edit: Now also the Africa_971_7520 has code and can be activated
