Appendix Appendix Ways to Charge Your nüvi • Use the vehicle power cable. • Use the USB cable. • Use an optional AC adapter cable. Calibrating the Screen If the touch screen is not responding properly, calibrate the touch screen. Turn the nüvi off and then back on. Slide the Power key to the right (lock). Hold your finger on the screen for about 30 seconds until the calibration screen appears. Follow the on-screen instructions. Resetting the nüvi If the nüvi screen stops functioning, turn the nüvi off and on again. If this does not help, slide the Power key to the left and hold for 8 seconds. Turn the nüvi back on. The nüvi should operate normally. 44 Locking Your nüvi Garmin Lock™ is a theft-deterrent system that locks your nüvi. Each time you turn on the nüvi, enter the PIN or drive to the security location. 1. Touch Tools > Settings > Security. 2. Touch the button below Garmin Lock. 3. Enter a 4-digit PIN and drive to a security location. What is a Security Location? Select a location you return to often, such as your home, for your security location. If the nüvi has satellite signals and you are at the security location, you do not need to enter the PIN. NOTE: If you forget your PIN and your security location, you must send your nüvi to Garmin to get it unlocked. You must also send a valid product registration or proof of purchase. nüvi 700 Series Owner's Manual
