@ Juiceme, Thanks for explaination

@ Maemish, I didnt remember Modrana QML version existance, don't even know what it is.
As maps, I am using OpenStreetMap, Google, sometimes Sat view but actually I don't use mapping nor routing very often.

But I noticed routing doesn't work at the moment...

In your case, getting a lock and displaying maps are two different problems which must be treated separately.

To test your gps/agps, try another map application or the one referred in the wiki as location-test-gui.

About Mordana display staying white, you can try to verify its configuration, launch it from terminal to see the output or even launch it with strace.
-Settings > Connectivity > Location > Network Positioning is supl.google.com, not supl.google.
-How does your /etc/hosts look?
Did you test positionning after rebooting and recheck Settings > Connectivity > Location > Network ? In my device, it sometimes comes back to supl.nokia.com by itself.
Did you try with gprs and wifi?
Is your device in phone mode with the simcard registered and active?
