Have you downloaded any Windows 10 Microsoft maps?
And what about Google Earth? Menu options on Google Earth are specifically to enable GPS.
Hi Sharpcolorado
Thanks for your suggestions. I really appreciate your taking the time to respond to a question that's not actually about the device you are using!
I've downloaded google earth and fiddled around with the GPS settings but all I'm seeing is a nice picture of the world - it's not displaying my location. However I've never managed to get to grips with Google Earth properly. I need to sit down and spend some time with it to learn it in detail. So the fact it's not displaying my location isn't necessarily a GPS problem - it could be user error.
I have downloaded the W10 MS map of Europe and I can display the map perfectly when I'm not in range of a network. But when I press the button at the right hand side to determine my location, I just get an error message saying "I'm sorry - I can't tell where you are at the moment". So I'm pretty sure it is only using the wifi / mobile signal too determine location, not the GPS signal. Similarly, if I use apps like "GPS Satellite", it will display my Lat and Long, but not altitude (it always shows it as zero). This, again, makes me think that location is determined by using network signals, not GPS.
