I have the same problem. Even with wifi on - it still thinks I'm located in Shangai. I tried updating the Google map from the android market and that did not work either. I tried the GPS attachment but it did not pick it up. I only have wifi on the tablet so I was offline when I was trying it out. Think I'll try it outside my house with wifi on. The directions are minimal at best and don't even have any info the GPS attachment.
I have a SAWEE pad. I don't remember the rest of it because I don't have it with me right now.
