First be sure that the map you want to search is the only one turned on on the GPS by doing the following:
From the main screen of your GPS choose Tools → Settings → Map → Map Info You will now see a list of all maps installed on your GPS and/or SD card. Uncheck all maps except the one you want to search.
In most emerging countries there is a lack of a central address system which can make navigation by the "address" more difficult, so we recommend NOT searching with the Address function. However, there are several other ways programmed into your GPS for finding a destination. You can navigate by:
Touching a location on the map
POI - POint of Interest
Latitude and Longitude (Coordinates)
Your own saved waypoints
All of these methods can be found on the "Where to" screen and they are fairly easy to figure out by simply experimenting with your GPS, but if you need more specific refer to your owner’s manual for your GPS. If you still need further assistance you can contact Garmin support; their contact information can be found at http://www.garmin.com/us/support/contact/ You could also send an email to firstname.lastname@example.org and will we can provide a more detailed explanation.
Your GPS will automatically show you maps, cities, and POI’s near your current location, so if you want to be able to view a map and search for cities, intersections, and POIs in a country different than the one in which you are currently located you must choose the “Near…” option after you select “Where To?”
click WHERE TO?
