if you mean the screen just goes blank but the gps is not turning off, go to the tools section (little wrench icon) then system then make sure safe mode is off.
if your 660 is powering off totally, make sure it is fully charged by charging it via the usb cable to your computer for a few hours.

- make sure its has a good charge,plug it in to the usb port on your computer for a few hours.
then try a reset
note: that the master reset will erase all your saved data
with
the unit off,and unplugged, try pressing and holding your finger on the low right
corner of the screen and slide the power switch to the on position
until you see the message "confirm if you really want to delete
all user data?" hit yes and let it restart. then it will set up the
nuvi again, so follow the prompts.
if that fails, hook up the nuvi to the web updater and get the latest update
(actually i would do this either way)
