when to call Position.getInfo()

Hi all,
As a beginner to Connect IQ, I am still trying different ways of reading location info as well as compass settings in a multi page app.
Currently, in my view, I have a timer event (1000 msec) based on which I call Position.getInfo() to read the current GPS info.
In my simulation everything works fine but in the actual watch (Quatix 3), position data does not seem to change at all :(
The question is whether Position.getInfo() can be called anytime or do I have to use enableLocationEvents first ????
Thanks for your ideas.

Ok, here's the way you do this. (just using position doesn't fire up GPS so the position never changes)

When you start up, you want to fire up GPS. Ie:

Position.enableLocationEvents(Position.LOCATION_CONTINUOUS, method(:onPosition));

(there is also a LOCATION_ONESHOT if you only need the current location and then GPS can be turned off)

The way I do this is then, in the "onPostion() function I have something like this (it's passed the current info when it changes):

function onPosition(info) {
		var latLon = info.position.toDegrees();
                ....
        }

in onPosition you can do things based on things like the signal quality, etc, and save off the current lat/lon in a class global.
