Garmin streetpilot c550 recharge

I got a garmin streetpilot c550 for Christmas and am having the same issue as other people on the sight where it just stopped working. How do you know if it is recharging on the computer since there is no sound or light on the unit and the computer can't find it?

Here is the fix direct from Garmin...

The following procedure will update a file in your C5XX and correct the power issue you are experiencing with your Garmin.
A.) Let the Garmin sit without power for at least 24 hours.
B.) Plug the C5XX into your computer (using a usb port in the back of the computer) with the cable provided with the unit. Allow the C5XX to charge on the computer overnight (with the computer staying on). Proceed to “C” the following day.
C.) After removing the face plate on the front of the Garmin press and release the reset button. At this time the C5XX will reset and power on.
D.) Update your unit’s software. To update your unit’s software, click on the following link - and click on Unit Software. Next click on DOWNLOAD. You will be given several choices to download. For most users, unless you know otherwise, select “WebUpdater Ver. 2.4.1 as of Apr 03, 2007 Download”. Next agree to the terms and conditions and on the last screen click DOWNLOAD again. If given the option to RUN or SAVE, click RUN. Next click Run to install the program to your computer. The first thing the program does is try to update itself. After that, attach your device (GPS) to the computer and follow the prompts to update your unit. If you are asked if you want WebUpdater to check for additional updates, select yes then choose only those updates that you need.

E.) After the initial update you will be asked if you want WebUpdater to search for any additional updates – select yes.

F.) When now doing a software update on the C5xx series using the WebUpdater, you MAY now notice an update available for the PLD software in the additional updates section. You want to download this update. This should correct the power lock up issue that we were seeing on these units. If you do not see this PLD software it is included in the regular update.

G.) Disconnect the C5XX from the usb cable and let the unit restart. A message will appear on the screen stating "Updating PLD Software".
Note: the screen will fade out and go blank during this process. Do no be alarmed, this is part of the update procedure, and the screen will return to normal within seconds.
Just as a note, when you connect the unit to the power cable in the vehicle, make sure the battery icon (next to the time on the Menu screen) disappears. If the icon does not disappear, the unit is not charging and you will need to check the fuse in the end of the cord. As a further suggestion, I would recommend you pull the power cord out of the cigarette lighter socket when the vehicle is not operating. This would prevent anything that could drain power from the unit having access to that battery power and leaving the unit dead.

Let it sit without plugging it in for 24 to 48 hours. After that, plug it in to the computer with the USB cable. If it doesn't power on in less than 5 seconds, it may need to sit without power more. After you get it to turn on this way, go to and download the WebUpdater. This program can help you update the software for your c550.

These steps worked for me and I haven't had any problems since. I hope it helps you.

HOW CAN YOU UNLOCK A CODE LOCKED UNIT if you dont have the code?

No, unfortunately. You either need to drive to the secure place to unlock it, or contact Garmin to have it unlocked. Once unlocked, I would recommend turning Garmin Lock OFF.

Forgot pin number

The only way to unlock a PIN locked Garmin is to enter the correct PIN number, or take the unit to the location at which the PIN was entered. Your only other option is to send the unit to Garmin.

Remove the front faceplate, (there is an indentation under the word Garmin on the faceplate that you can use to lift it with your finger nail). After removing the faceplate you will see a reset button on the right side. Press the reset and then try to turn the Garmin on.

Hi Don,


You probably just need to find the reciept where you bought the C550.  Sounds like Garmin is protecting its customers when they say $300.  This is most unfortunate thing to happen to you.  Is the Garmin $300 issue as I thought and related to you not having the registration code or Reciept?
