How To Reset Your Garmin

I needed to reset my Garmin 1390 GPS unit, before giving it to a friend, to erase all of my personal data.  I found out there is a nice factory reset function which will clear all user data.

To factory reset your Garmin:
  • Power off the unit
  • Press and hold the lower right corner of the screen
  • Power on the unit.

I also found that if you do the same thing but press and hold the upper left of the touch screen, it will re-calibrate the touchscreen.
