libqtm-location is a wrapper of liblocation, which does not provide information about magnetic variation, seems to cause errors in this. So that attribute is always invalid.
What you don't understand is, there is no NMEA data from the device. The GPS talks to a user space library call liblocation in a binary protocol. liblocation is then wrapped in the Qt Mobility location APIs. I'm pretty certain that the GPS receiver isn't capable of generating NMEA itself.
