Hi, i'm a new member so please be patient with me. lol. I have downloaded garmin XT for europe and installed it on my N95 and it's all working great. I'm spending a month in thailand soon and was going to download some thailand maps. Is it possible to just add the thai map to my SD card so that i can view europe and thailand. Or do i have to just use one map or the other, i.e just Thailand, or just Europe ? Or can i merge them together in anyway ? Any help would be great thanks. craig
