I just got the ZUMO 660 and some GT-Rider members showed their interest, so below I post some info and pics. 
The ZUMO 660 is not sold by ESRI yet, so the Thai map is not preloaded on this unit.
The ESRI map can be ordered;
1. Waiting time: 3-7 days
2. In English only
3. Price: 4.500 THB
4. Free updates during 1 year.
I'm impressed with the accessories for this unit. I guess some of you had the experience with Street Pilot 2610, which did not have bike mount included. For zumo 660 Garmin added RAM mount (see the pics below).
If you have any questions ....
What's in the box (see pics below):
* zūmo 660
* Preloaded City Navigator® for Europe (full coverage)
* MapSource® City Navigator City Navigator Europe NT DVD (full unlock)
* Motorcycle mount with integrated power cable and mounting hardware
* Carrying case
* Battery pack
* Automotive suction cup mount
* Automotive power cable
* USB cable
* Dashboard disk
* Quick start manual
