Actually, hydetech is correct. The only way to unlock the unit is with the PIN or taking the unit to the location at which the PIN was set. Your only other option would be to return the unit to Garmin.

Impossible to unlock without knowing the PIN or the location of the GPS when the PIN was activated.

Need to change pin number in garmin nuvi model 205 i bought it at a police auction and need to enter my own pin number

You will need to contact garmin to do this. Their website is when you get to there web page look at the top right hand corner where it says My garmin. From there set up a new account once you do this then contact their technical support either by phone or by email. From there they can instruct you what you need to do to reset the pin number.

I hope this helps you out and if it does please give me a YES on the page you receive my response on. Thank you

I have a Garmin Nuvi 660 that I purchased from a police auction that requires a PIN to work. I don't have the correct paperwork for Garmin tech support to help.

Garmin will only unlock devices if you have proof of purchase.
Think you need to go back police auction and get correct paperwork.

Just bought a Garmin GPS. Where do I find the PIN number to use it for the first time?

If it is asking for a PIN number, then the unit has been secured by the previous owner. If you bought it new, take it back to the store for a new unit. If you bought it used, you cannot change the PIN number. Only Garmin can unlock it and you will need an original receipt from a licensed Garmin dealer to unlock it and they will probably charge you for this service. This is a security feature so that the unit cannot be used if it is stolen.

Lost Pin for Garmin Nuvi 360

Unfortunately without the receipt you won't be able to make this work. When a Garmin PIN is set the user is allowed to pick a location that they can go to in case they forget the PIN. If they turn the unit on while at that location the unit will not ask for the PIN. The only other way to reset the PIN is to sent it back to Garmin. If it was bought at a police auction they would have supplied you with some kind of a transaction record. I would call Garmin Support at 800-800-1020 M-T 8AM-6PM Fri 8AM-5PM Central time. Explain the situation to them and they might be willing to fix it for you. Normally if they are sent a GPS that doesn't come with a receipt they will contact the Police in the registered user's area. Good luck.

Garmin nuvi 300 asking for pin number

Unfortunately, even if you perform master reset on Garmin GPS unit, it does not reset Garmin Lock security feature, which password-protect most Garmin electronic devices to deter theft. If you forget the PIN or password unlock code to unlock the Garmin unit, the best solution is to bring it to Garmin to get unlocked. “Secure Location” does not unlock a locked Garmin unit either as it’s only a temporary fix as when it’s turn on outside the security location, the device is locked again."

So unfortunately, there is only one option: You have to send your nüvi into the Garmin, who can unlock it. Remember original receipt.

The only way to do it is to go to the location you set as "home" in the GPS. When you are at that location, the GPS will not ask you for a PIN and you can then go in and change the PIN.

If you don't know what the home location is, you'll need to contact Garmin

There are so many of these being stolen from vehicles, the PIN is designed to make the unit useless to thieves.

Good luck!

Pin number

There are only three ways to unlock the GPS.

1) Get the PIN from whoever you bought it from.
2) Take the GPS to the location it was at when the PIN was set.
3) Send the unit to Garmin to have it reset. For return information: CLICK HERE

If you can't get the PIN from whoever sold it to you online, it is probably a stolen unit. You should contact your local police dept with a the serial number to see if it turns up in their database. If it is stolen, you may be eligible for a refund from the online auction house because you were defrauded. At the very least you should file a complaint with the auction house to prevent this sub-human from screwing other people the way he screwed you.
