It appears the Thailand map on SD card from Garmin has been discontinued. I guess now ESRI will be the only source.

They do however have a Southeastern Asia Map which includes "Select Areas" of Malaysia, Indonesia, Hong Kong and full coverage of Thailand. I would guess it is probably the same coverage of Thailand that was on the other SD, and they are just trying to increase the market area.
