If I'm understanding your questions, you need to know how to retrieve a previous location search. If that is the case, Google Maps automatically saves all location searches. In order to retrieve a previous location, just start typing the address and you should see the entire address popup in the drop-down list, where you can re-select it. At least that how it works on my Eris. Regarding the "My Location" option. In order to update your "My Location", make sure GPS is turned on and then click on "Menu" and then "My Location" again. This will update your new location everytime you select it. Hope this helps.
