I try to use the Dual Unlock map with Garmin Thailand iPhone Version but it doesn't work. In the version 12.1 Dual has no problem. It only can detect Unlock 3D map.
Has anyone try this out. Please advice.
OK. Now I am able to insert the new map, 3D Map and JCV into "Garmin-THA_Onboard.ipa". Not the original Garmin Thailand. It is the Onboard version. everything works fine.
