Does anyone know why the French islands like Guadeloupe, Reunion etc are just partly represented on the maps when istalling the France map. Navigation data seem to be there (at least in part) and some Microlight airstrips but not the main airports like Pointe-a-Pitre in Guadeloupe or Roland Garros in Reunion for example.

We simply don't maintain data for those areas, sorry. If there's a lot of GA that happens there, please do get in touch with us, as perhaps we could look into adding that support.
