Putting a Garmin Dash Cam 10/20 into Mass Storage Mode

The Garmin Dash Cam uses mass storage mode to communicate with the computer. A microSD card must be inserted into the Dash Cam before it will go into mass storage mode.

When plugged into a computer with a microSD card inserted, the Dash Cam will ask if you would like to use it in mass storage mode. Press the button under OK to confirm. If you press the button under Cancel, the Dash Cam will remain on and record video as if it were connected to the vehicle power cable.

Mass storage mode is indicated by this icon on the screen:

If a microSD card is not in the Dash Cam while it is connected to a computer, or if the card is inserted after the Dash Cam has been plugged in, the device will power on but will not display the prompt for mass storage mode.
