Help me.......i put a pin number on my garmin nuvi 660..and i cant remember what it is...Is there any way to reset it and start over..

All you have to do it take the gps back to where you were when you entered the pin # . It will then start up and you can either change the pin or just set it to where you won't have one .
This is done so that when IDIOTS steal them , they can't do ANYTHING with them,

Cant enter pin or screen is frozen

Look near the SN # and press the reset button.


with the garmin off, hold down the right bottom of the screen and turn the garmin on, it will then ask you if you want to perform a hard reset. Choose yes and that should fix your problem.

If you start it up and are located in the place where the pin code was set, then the unit should unlock once it acquires sufficient satellite signals.

Unlocking security code

The first thing you have to do is enter the correct PIN or take the unit to the location at which the PIN was set. It will now unlock. You can then press the icon that looks like a wrench, and look for an icon that says Garmin Lock (it is in different places on the different units, and I forgot exactly where it is on the 660, sorry.) You can then change the security code from there. If you are trying to unlock the unit without the PIN number, you will be unable to do so without taking the unit to the security location. In that case, your only option is to send the unit to Garmin.

Hi can you help /

You can try a master reset. With the unit off hold your finger on the upper right hand corner of the touch screen and tap the power button.  Continue holding your finger on the screen until you see a message "This operation will erase all waypoints, do you want to continue?" (this could take up to a minute)

Tap yes and the unit should reboot then attempt to acquire satellites.

Garmin nuvi 660 forget my pin

The only options you have when it comes to a locked unit is to enter the correct PIN, go to the location where the PIN was set, or send the unit back to Garmin. There is no way to unlock a PIN locked unit without the correct PIN or location.
