Information about USB Drivers
The USB drivers should have been automatically
installed when you installed the MapSource program
that came with your 76CS Plus. When you initially
connect the 76CS Plus to a USB port, your computer
may prompt you to locate the destination of the driv-
ers for the device. You only need to install the drivers
once. After the drivers are installed, your computer
will always detect your 76CS Plus when it is connect-
ed. USB drivers may be updated periodically. You can
fi nd these updates at www.garmin.com.
