Second of all, due to the link above, I don't understand exactly what you want. Allow me to attempt to clarify:
You want the player's camera to view the San Andreas map that is in the Area 69 map room, and allow them to place icons on the map?
For that you need to set the player's camera with SetPlayerCameraPos and SetPlayerCameraLookAt, you'll need to use GetPlayerKeys in OnPlayerUpdate to detect the movement, and OnPlayerKeyStateChange to detect the key for placing/removing a marker.
You'll need to use objects for the markers, these are the 'mapicon' objects:
https://sampwiki.blast.hk/wiki/Samp_objects search that page (Ctrl+F) for 'MapMarker'.
Good luck, it's not the easiest of things you're trying to do. If you a beginner you should ask someone to help you fully, i.e. over teamviewer/MSN/skype/whatever.
EDIT: Or instead of viewing the area 69 map, do you want the map to appear as an on-screen sprite? You'll have to use textdraws for that.
