Problem/Question Solution/Answer
My computer
never detects the
GPSMAP 620 when I
connect it.
1. Unplug the USB cable from your computer.
2. Turn off the GPSMAP 620.
3. Plug the USB cable into a USB port on your
computer and into your GPSMAP 620. The
GPSMAP 620 automatically turns on and
goes into USB mass storage mode. Ensure
your GPSMAP 620 is connected to a USB
port and not a USB hub.
I cannot see any new
removable drives in
my list of drives.
If you have several network drives mapped
on your computer, Windows can have trouble
assigning drive letters to your GPSMAP 620
drives. See your operating system Help file to
learn how to map or assign drive letters.
