You can separately use both the PC installed mapping data in BaseCamp as well as the .img file on your device or card when connected to computer. The PC installed data is used to compile an img file map to send to the device or media card so no need to buy an img as download or sd card if you get the DVD.

And another question, on the Website you linked it says this under "Overview"

(DVD only) Includes MapSource® computer software that lets you plan trips on your computer and transfer waypoints, routes and tracks between your computer and your device.
And I thought that MapSource wasn't used anymore
Don't use MS for installing maps on a device or card, but it's still fine for waypoints and routes etc. Use only MapInstall for sending map data as an img.

A good idea with me buying a cheap GPS back in Europe, but then I have the same problem but then other way around.

Would the GPS I buy there be compatible with the Thailand ESRI Maps (CN Thailand) ?
It might have a problem with the Thai only map, but Dual version should be fine. If that's not right i'm sure a local TH member will correct me or you could ask about compatibility for US/EU firmware units in the map thread: [Only registered and activated users can see links. ].

Of course you could also save yourself many baht here: [Only registered and activated users can see links. ].
