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"
You have to navigate to get to the good.
