I think there is some hard limit for the number of waypoints stored...
The 60CSx is limited to a total of 1000 waypoints. Since geocaches are nothing but waypoints with a treasure chest icon, there is no way to store 1800 waypoints, with or without the Geocache function, on the 60CSx.
You can store an unlimited number of Custom POIs (limited only by memory card capacity, anyway), but the Geocache function doesn't apply to POIs.

May be with the next firmware I¨ll be able to store more over 1000 waypoints (the best way - on the storage card)
