What map do you use in Nuvi1490. My Nuvi 1490 TH used Tsm 11.0 TH or EN and gmapbmap 4.00DEM if you use gmapbmap 5.00DEM and Tsm 11.0 DUO it will shutdown when you navigate. Sory I don't test with traffic receiver so Idon't tell you what happen and I want to know when you simulate driving does it can show JCV and Lane assist.
The 006-D2225-00.bin is a Thai font for 1460 TH you will copy it to ExtData folder.
