Information about USB Drivers
The USB drivers should have been automatically installed when you
installed the MapSource program that came with your GPSMAP
276C. When you initially connect the GPSMAP 276C to a USB
port, your computer may prompt you to locate the destination of
the drivers for the device. You only need to install the drivers once.
After the drivers are installed, your computer will always detect your
GPSMAP 276C when it is connected. USB drivers may be updated
periodically. You can find these updates at www.garmin.com.
