How to do a full backup on Garmin DriveAssist 50

Is it possible to do a full backup on DriveAssist 50 ? I cannot find the .system folder despite I have checked off the hide Protective files in Windows 10. Thanks

    Did you change the Drive from the default MTP mode to Mass Storage Mode?

    1. Start NUVI by itself and go to Speed setting on the Map Screen
    2. Press the upper middle of the screen where the Speed is shown for 10 seconds.
    3. The Developers Screen will pop up
    (may see Configuration and Settings, if so select it)
    4. Scroll down to MTP SETTINGS
    5. Change from MTP AUTO DETECT to MASS STORAGE and save
    6. Shut down NUVI and connect to PC
    7. It should now connect in mass storage mode.

    You also need need to set it to show system as well as hidden files.

    Thanks all for the instruction.. It works after I changed the MTP mode to Mass Storage Mode.

    t923347 : For the DrivAssist, I donot have the speed menu.. I have to bring up the Developer menu thru the "Volume" main menu.. Cheers

    Glad you got it to work for you.

    I have a Drive system and like all the Nuvi models there is, by default, a Speed icon on the lower part of the Map Screen. Tapping on that icon will bring up what I call the Speedo screen. Press and hold the Speedometer read out in the top center of the screen until the Diagnostic pages appears.

    Tap Configuration and Settings and on that page tap MTP Settings.
