Thailand Map For Mio H610

Hi All.

We'll be living in Krung Thep from the 16th August this year (partner's landed a 2 year teaching contract in a school).

I was looking at a good option for a handheld GPS device that I could use in Thailand. I came across the Mio manufacturer (never heard of them before) but I can't see if I can get Thailand maps for it, which kind of defeats the object!

Does anyone know if you can get Thailand maps for the Mio H610?

If not, can you suggest another alternative for a handheld Thailand comapatable GPS device?

Thanks
