I've been advised that one can change the GPS (internal or external) that an iPhone/Pad looks at for maps/charts apps etc.
I was told you can change the source in Location Services, but can't find it in Settings. Is this possible?
It's a iLevil Sport AHRS: http://goo.gl/NdRLDD with relevant apps to make it compatible and display data on the iDevice via WiFi.
Thanks - I'll try that and report back.
However, how does the iDevice (or I) know whether it's taking the GPS data from the AHRS or it's internal GPS receiver?
OK, thanks for the detailed information - I'll report back.
