I did a quick comparison of the two. Apparently, they were compiled by Garmin at different time, with different options (such as number of map levels), although on the same date. As far as I can tell, the size reduction in CN-NA is mostly due to a better encoding scheme used to compress road and POI names. The decompressed map data should more or less the same in both CN-NA and CN-SA.Quote:
