Origin of the device: official Thailand device or from other country
Firmware: version and language
Map: version and language (dual or Thai only)
JCV: version, filename, resolution, is it created by GarminAsianJCVTool.exe?
Locations: coordinates of the locations where JCV does not work

Lastly and most importantly, keep everything the same except replacing the JCV file with the corresponding official unpatched JCV file and see if you get the same or different results. If different, can you upload your patched JCV file for debugging? Thanks.
procedure: (Tried on both English and Thai interface)

1. NUVI2595 (US Firmware) used 2013.30 DUAL MAP Unlocked + patched JCV (THGLB.JCV) : can display jcv's images at a crossroads correctly. (on original jcv shown pirate copy)

2. NUVI3597HD (US Firmware) used 2013.30 DUAL MAP Unlocked + patched JCV (THGLB.JCV) : on the junction nuvi will restart. (as same as original jcv)
