Hi,
I tried that qml without luck, even with some reworking. There may be other issues with it. Here's is a sample that works for me:

You can get this to work with a project based on the default empty project template in the Momentix IDE (File -> New -> Project... -> BlackBerry Project -> Cascades Application -> Standard empty project) simply by replacing the content of the project's main.qml file with the code above. Also, you must add location permission to the bar-descriptor.xml file:
<permission>access_location_services</permission>
And make sure Location Services is enabled on device (Settings -> Location Services)
Hope this helps,
Jim
