I am developing GPS based Location reminder in j2me. I am little bit confuse to which maps i use??.....Google maps & Nokia maps. Which one is better?

The working of my app are as follows :-

-User will provide a string to app to search a place of his/her desire.

-Then according to given string app will show a place on map by pointing marker on map.

-User can save that place or he/she can select a near by place rather than searched place by clicking on map or any other way.

-app will save that searched place coordinates & remind when it reached to near that place.

-When app remind to user about already stored place... that place should show on map by pointing an marker along with the how far he is from his destination.
