Garmin GPSMAP 620 010-00762-00 Manuale Utente

Appendix

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.
