Trying to put maps on extSdCard on my I9100, 4.1.2 Stock, nonrooted; (on internal sdcard SP worked ok)
Used StreetPilot 2.22_extSdCard_noroot_add_th.apk and copied to extSdCard; SP installed and worked.
BUT wherever I put my Map folder on extSdCard, SP does not see any maps.
Tried file structure like Post 1: extSdCard/Garmin/System/gmapbmap.img
and numerous other structures to no luck.
Any help appreciated.
