You cant reset pin by taking apart the garmin nuvi 1340 then under the sealed...
I've seen many postings from users who say they have lost their PIN code.
For those of you that don't know what a PIN code is:
Garmin provides a feature called "Garmin Lock", which allows the GPS owner to assign a (4) digit numeric unlock access code or PIN to their GPS.
The PIN is designed to prevent your GPS from being used by an un-authorized user. It was also meant to be used a a deterrent to thieves, making the GPS useless if stolen.
The PIN setup can be accessed by pressing the "wrench" symbol on the main menu (Nuvi Series). Next, press the "gear" symbol and you should see a listing for Garmin Lock.
When you set up the PIN, you will be asked to enter in a (4) digit numeric code. After you enter the 4th digit, you will be asked again for the code. This is to make sure that both entries match and that verify that the PIN that you request will be the one written into memory.
Your PIN is written into non-volatile memory..... it's not a file that is accessible via USB communications between the GPS and a PC. You can't clear it by disconnecting the power or disconnecting the battery or letting the battery run down. There is no jumper or switch inside the GPS to reset it, so don't waste your time tearing the GPS apart.
Now, after you set the PIN, you will be asked to set the "secure" location. This can be anywhere.... your work location, home, local gas station, school, etc. In order to set the secure location, your antenna must be up and you have to have a satellite lock. If you don't have a lock, the "set" key will be grayed out until you acquire a lock.
The secure location is your "back-up key" in case you forget your PIN. If you have forget your pin, all you have to do is physically go to the secure location. Make sure your antenna is up and that you have a satellite lock. When you are in the secure location, your GPS will NOT ask you for the PIN when you turn it on. You'll then be able to reach the main menu and change the PIN and secure location to something else if you desire.
If you have forgot both the PIN and secure location you are out of luck. You'll have to send your unit back to Garmin to have it unlocked. Garmin may charge you for this service.
Note: If you do send the unit back to Garmin to be unlocked and you are found not to be the original owner of the GPS and it's determined to be stolen, Garmin will contact law enforcement (they're policy on this is right on their website under FAQ's).
