    Master reset on nuvi 37xx series devices :

    1. Power off the unit (press/hold the power button for ~7 seconds)
    2. Power on the unit
    3. When the Garmin copyright screen is displayed, press & hold the bottom-right corner of the screen
    4. Release the screen when "Do you really want to erase all user data?" appears
    5. Touch "Yes"
