My nuvi 680 screen is frozen - Garmin Nuvi 680 GPS Receiver

SOURCE: Garmin nuvi 680 unable activate bluetooth

I did the following steps and my Nuvi 680 bluetooth is working good now.
Please try these:

Thank you for contacting Garmin International, I am sorry that you are having this issue. You may need to reset your
BlueTooth:
1) From the Nuvi main "Where To?" screen, tap "View map"
2) On the map screen, tap the "speed" indicator in the lower left corner of the screen.
3) On the next screen, there is a large round speedometer (mph) near the top center of the screen. Press and hold on the center of the speedometer until the screen changes to a diagnostic mode that says "Shutdowns" at the top.
4) Press "Next"at the bottom of the screen repetitively until you come to a screen that says "Bluetooth statues" at the top...
5) On the Bluetooth Statues screen, press "Updt PR" button in the lower right corner. The screen should show "Do you really want to update the Bluetooth firmware?"... Press "yes"... Let the unit sit for several minutes. It should show "Updating Bluetooth on the screen. When it is complete, it will return to the "Bluetooth Statues screen.... Press "Quit" in the lower left corner... Then return to the main "Where To?"
screen and try enabling and paring the Bluetooth again?.
Additionally, it is best to pair the devices from the cell phones menus and pairing procedures, instead of from the Garmin device......
Note: before re-pairing the Nuvi to your cell phone, make sure you remove the nuvi device fr your cell phone first, then add device. If your nuvi bluetooth still fails after you do this step, then your nuvi bluetooth file maybe corrupted. You will need to download this file and reinstall it to your Nuvi

SOURCE: unlocking a garmin nuvi 680

Here's your options:

1. Enter the correct PIN.
2. Go to the secure location where the PIN was set and it won't ask you for a PIN.
3. Send the unit back to Garmin to be unlocked.

Sorry but there is no master reset. The PIN is written into memory that can not be erased. I have had success in unlocking Nuvi's but I will only do it for people who have a valid purchase receipt from a major retail chain and if they can provide me with their Garmin registration info so I can verify that they are the rightful owner.

There are too many of these units out there that are stolen and the culprits are looking for a way to bypass the PIN. This is why Garmin added this feature to their GPS's.

Hi,
When you first programmed the GPS you have the opportunity to select a safe location,
if you selected the safe location, go back to that location, and the lock will not be on, it is for the reason of forgetting it, but it will only work in that location ~ ( ie: your old driveway )
If you cannot do this,
it's a Garmin job to unlock it,
There is no other way to unlock it.

Regards
Richard.
