Information About USB Drivers

The USB drivers should have been automatically installed
when you installed the MapSource program that came with
your GPSMAP 378/478. When you initially connect the
GPSMAP 378/478 to a USB port, your computer might 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 378/478 when it is
connected. USB drivers might be updated periodically. You can find
these updates at www.garmin.com.
