Map API

Hi to the community!

I just start working with Titanium and i try to understand how the Maps API works, i have create a Map and i pass the 2 Annotations p1 and p2, in the Ti.Map.createView i set to true the userLocation, i pass the lon and lan vars to (p1 and mapview have the same latitude, longitude),

but the current position of the p1 is not the same with mapview,

how i can attach the p1 annotation to the mapview as the current position and also, how i can change the "Current Position" title in the mapview?

i'm using Ti SDK v1.8.2 on Mac

here is my code:

var lat = 37.30168900;
var lon = -122.03073100;
 
var p1 = Ti.Map.createAnnotation({
    latitude: lat,
    longitude: lon,
    title: "C.Norris",
    pincolor: Ti.Map.ANNOTATION_GREEN,
    animate: true
});
 
var p2 = Ti.Map.createAnnotation({
    latitude: 37.318844002395444,
    longitude: -122.01622009277344,
    title: "Samurai Master",
    pincolor: Ti.Map.ANNOTATION_RED,
    animate: true
});
 
var mapview = Ti.Map.createView({
    mapType: Ti.Map.STANDARD_TYPE,
    region: { latitude: lat, longitude: lon, latitudeDelta: 0.05, longitudeDelta: 0.05 },
    animate: true,
    regionFit: true,
    userLocation: true,
    annotations: [p1, p2]
});
 
win.add(mapview);

thanks a lot!
