I tried to fix a problem similar to this for 1and 1/2 hours. Ahhh! However, after raising the antenna, (in back of device), the satellite picked up my exact location. Hope this helps.

Here's a video demonstrating how to change the Nuvi 660's battery from newpower99. I hope this helps. Peace, Craig

This is because your map file has either been deleted or corrupted and needs to be replaced. Please see this link for more info. Too much info to copy & paste here:

Try pressing the reset button underneath the antenna and if this doesn't help, then you'll need to have the LCD display replaced.

If the Nuvi won't charge when connected to charge but charges on USB, then the charger port is faulty.

If the Nuvin does not charge at all , then the battery must be replaced.

Drivers for Vista are there

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.

Resetting the unit does NOT reset the PIN. Even a Master Reset will not reset the PIN. You have three options for unlocking a PIN locked Garmin:
1 - Enter the correct PIN
2 - Take the unit to the location at which the PIN was entered
3 - Send the unit back to Garmin

You didn't say how long you've had your device, but if you haven't registered your device at Garmin.com yet, go do that and they will then offer you a free upgrade.

Other than that, I don't think you'll find anything free. The next best thing is to buy the "nüMaps Lifetime™". I felt this was the best deal they have.
