John , With changes made the POI data and the increase of the total size of the USA from 7GB to 10GB, this means that it is no longer possible to fit California onto a 1GB card nor it is it possible to fit the entire USA onto a 8GB card. This is the reason Sendero has began to offer 16GB cards as their default card size.
