We are trying to modify it to use with Thai map with Thai Fonts. Originally, it will show ????? on map.
This program didn't come with Thai Font so we modified "garmin-nav" in garmin.app by replacing font 1 and font 3 with Thai Font.
It works great on iOS4 and earlier but unable to get into the app on iOS5. I'm not sure if it has any "checksum" something on iOS5.
Any modification of "garmin-nav" will cause this problem on iOS5.
Please help....
