Maybe this has been covered, but I cant seem to find any explanation in these forums, and yes I have searched all over here and google.

Can anyone give me instuctions on how to fix the China GPS offset problem?

I am running Garmin Mobile XT on my Windows mobile phone. Ive heard something about modifing the settings of gmsup to china or change the MapID, but i dont know how to do either of those. Or using QSI instead of NT maps, but i dont really understand this either. Sorry, im a total newbtastic at this stuff.

Any help would be greatly appreciated
