My Location works with 'cell' masts and does not need GPS. Works indoord with no set up on my StrTrk which certainly doesn't have GPS!
i just figured out what you are trying to say. its not that i was listening to you, its because i didnt understand what cell masts were and the idea that my location does work without gps. as i was fiddling around with my google maps, i stumbled upon something interesting. i found "disable my location" under options. i wanted to see what would happen. when i clicked on it, a rather long text comes up explaining the benefit of my location. it goes on to explain that, and i quote "... but there maybe some areas where our coverage is incomplete; if you get an error message when trying to access your location, don't worry--- it should work in other nearby locations..."
is it possible then that people who are getting the "your device is not compatible" message live in incomplete coverage areas?
im not trying to disprove you, im just trying to understand this whole gps thing and you seem to know more about it.
