Hi i've got nuvi660 bit oldi but still works ok. On main memory have map CNAuNZ 2012.1 an try to add on SD card CNEu2012.10. Downloaded MapSource unlocked with "unlock_mapset.exe" with no errors all went fine. Created custom map cut out Eastern country and Island so the whole can fit on 2GB card. Took little while to do it , but eventually
success ! All works perfect. So I decided to create full map on 4GB SD card , took little bit longer MapSource program ver. 6.16.1 did not complain said successful transfer to SD card
map are visible in my nuvi under /system/maps/info but can't select any address from this map ? As I said both maps (images) been created from the same ma source one works ok
the other not ? , about 300MB difference in size. Question: what max map size image nuvi 660 can accept ?
