Pin number i bought a garminc550 gps at a flea market it is asking for a pin number. How do i unlock or reboot it

Use google to find the procedure of shorting the bios pins it sounds alot harder than it actualy is

Unfortunately, you cannot unlock it. It can only be unlocked by the original owner with either a PIN or taking it back to their 'security location' which they set. Otherwise, you have to send it to Garmin with the original receipt from an authorized Garmin dealer and they will unlock it for a fee. If you/gift giver got this from a flea-market, it looks like you are out of luck in unlocking it.

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.

Probably a stolen Garmin GPS. When I was living in Indianapolis last year, they were breaking into cars all thru my neighborhood just to steal GPSs. Cost me $225 to have my driver's side window replaced. Cost me $180 to replace the Garmin and my iPod. Should've left the car unlocked and let them have it. Would've been cheaper.
No, I can't help you bud. Don't know how to clear that password. Maybe you can send it back to Garmin and they can do it.

Take it back and get your money back, as it is probably stolen. The PIN cannot be broken as it is set by the original user and cannot be reset by a third party. Even Garmin will not reset it without the original receipt from a Garmin dealer.

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.

There is no such thing as a Universal unlock code. Please see my article that I wrote on this topic. There is a chance the item you purchased was stolen.

Owners can select a pin code to use which locks the unit preventing use by theives. Sat Nav theft is a big market. The unit needs to be sent to Garmin who will verify you are the registered owner and unlock it for you. If you bought at a market is there a good chance it may have been stolen?

Your first problem was purchasing the unit the way you did. If you purchased it legitimately, you would not have this issue. Your only solutions are to enter the correct PIN number, take the unit to where the PIN was set, or send the unit back to Garmin.
