NT maps was first introduced when memory storage and memory cards was very expensive. In 2004/2005 you would have to pay ~700 USD for a 4 GB memory card.
Garmin uses NT format to protect maps from editing and stealing details by other map makers. OF / non-NT (old format / legacy format) maps can be edited by some map editor tools. The map data is normally the same in the NT & non-NT maps but some details might be removed in non-NT maps if it's close to 2 GiB in size. Older units have a 2 GiB limit of file size for map files.

aaahhh... i see... thanks for the info.

"It contains Taiwan Map, Taiwan Address Point 2010.3F."

After downloading and extracting, I got 2 img files. I believe the 70MB one is Taiwan Address Point file. Can anybody explain what Taiwan Address Point for?

Is this suitable for nuvi200?
Thanks,

as i know NT map is official map from Garmin with a few POIs...can i know where to find a map with all POIs suitable for a traveller?or where to find POIs which can be restore to the NT map..

thanks in advance

For some reason, this doesn't work for my Nuvi 680. My 680 doesn't display Chinese Characters. Are there ways to update my 680's firmware, so it reads both Chinese and English? Thanks.

You can tryto flash to TWN Model 660. I haven't seen any support files on Taiwan website for download together with the software.

Does this work with a US based Garmin 1350?
