Thread: Garmin Thailand Street Map NT v10.0 EN+TH ( IMG Unlocked)

Anyone please help!!!

My gps is 255w originally US firmware but I converted it to sg/my 2.80 firmware. What I installed are Thai kb, Thai menu, the map (Thai version as a gmapprom), and the D1229030D JCV files.

I have a weird problem. When I use it in Bangkok, everything works great. I can use all fuctions such as Jucntion view, highway mode (choose malaysia locales). But last week I brought this gps with me to Chiang Mai. When I tried to use it, the GPS coundn't calculate route at all no matter from POI searching or putting a new address of somewhere in Chiang Mai. I mean no route calculation, no pink line and the GPS just keep showing the messege "unable to calculate route to destination". However, when I removed the JCV file, the GPS worked normally again.

Also,I try to use it as a "OFF Mode" and it shows that when I put the JCV file in the Unit. I can't simulate a route at all in every province of Thailand except in Bangkok.

I doubt that this problem happened because I didn't install the Thailand basemap providing in this thread. When I check the basemap file, it is still the old one from US version (around 50mb). But I don't know that when I flash it from US to SG/MY firmware. It replace the basemap to SG/MY version or not.

So, what I wanna try is deleting the old basemap (50mb) and I'll put the new one that provides in this thread but the Rapid link seems not to work. Could anyone please upload the Thailand basemap 3.00 in this thread again. Also, is my suspect right about this problem? Anyone please help and sorry for my English. Thanks in advance.
