I apologise if this question is too basic, but I couldn't find the answer. I plan on buying a GPS soon. I will go to Canada next month where I can buy any Garmin GPS unit for 20% to 40% cheaper than I can buy it in Thailand. If I buy it in at the GPSforyou shop in Fortunetown on Rama 9, they will load the Thailand maps there (I'm not sure of the cost). 1) Will the GPS work in any country, as long as you load the necessary maps? 2) Can you load the Thailand maps in (Thai and English) on the device after buying the GPS in another country (such as Canada)? 3) Where do you buy the maps? On the Garmin website? 4) does the GPS connect connect to the satellites without any wireless service? Thailand still doesn't have 3g, so I've given up trying to use the gps on my Android phone.
