On Android phones like Samsung Exhibit II 4G, an external SD card is not treated as external storage from Android's view point. Therefor you cannot update Copilot maps in the app because there is not enough space on the "USB device". Here is a walk around.
1. Install Copilot app on the phone.
2. Copy the app folder to the SD card use an app like ASTRO
3. Get the map to the external SD card. Two possible ways:
a. Using Copilot Central on a PC, if the map is available through it.
b. Download the map from a different device which has enough space.
Either way copy the map to the external SD card.
4. Edit the user.cfg file on the phone, change the path to the maps.
