New maps are released every 3 months (February, May, August & November). The first 3 digits
(930) are the Edition. Each new edition goes up by 5 digits. The February 2014 edition was
(925). The May 2014 edition
(which is current) is
(930). The August 2014 edition will be
(935). The answer to your question is, start with Edition 930 & go back 3 months & 5 digits at a time, until you get to the map Edition on your SD card.
