Question about Garmin StreetPilot c550 GPS Receiver

Won't turn on after first time

I used my Garmin c550 right out of the box without charging the battery. I plugged it into my car with the AC adapter and it was working fine. When I turned the car off, it shut itself down after 30 seconds. After that, it would not turn on. I've had it plugged into the computer for over 10 hours to charge the battery, but it still is not turning on. (The device did not automatically power on when connected to the computer.) I've tried pressing the power button, holding it down for over a minute, pressing the reset button, simultaneously pressing reset and power, and nothing has worked.'s support page won't load and it's past customer service times (will call tomorrow). But just in case customer service can't help, I'm wondering if this has happened to anyone else, if I'm doing something wrong, and if there is a way to fix this.

Re: Won't turn on after first time

Saw this on a different forum.....I got one for xmass.....hope it doesn't happen to me!!!!!!!!

I apologize for the inconvenience. After further research with our engineers, a problem has been discovered on your C550. A file has been created to stop the unit from turning off and locking up. Please download the new file from your computer to the unit. The file is attached to this email along with instructions on how to get the file into the unit.

The following procedure will update the software in your C550 series and correct the power issue you are experiencing with your Garmin C550 series

1.) Let the Garmin sit without power for at least 24-48 hours.

2.) Plug the C5xx series into the your computer (using a USB port in the back of the computer) with the cable provided with the unit.

3.) After removing the faceplate on the front of the Garmin press and release the reset button. At this time the C550 series will reset and power on.

4.) Save the attached file included in e-mail from Garmin Product Support. Save this file to the desk top on your computer. Note: This will make it easy to find.

5.) Open the My Computer window (by accessing the start menu on the bottom left of your computer screen).

6.) Locate and open the Garmin Mass Storage device.

7.) Locate the Garmin folder and open.

8.) Open the remoteSW folder.

9.) Copy the file that you have saved to the desktop and paste it into the remoteSW folder you have just opened. Make sure that none of the files contained within the remoteSW folder is highlighted, or you will not be able to save the new file.

10.) A message window will pop up asking you to confirm that you want to replace the file; Select Yes.

11.) Disconnect the C550 series 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 not be alarmed, this is part of the update procedure, and the screen will return to normal within seconds.

I will be travelling in Europe without a car and no access to a computer. Is there a plug in adaptor for charging the battery? Can the battery be replaced, as needed?


You can purchase AC international adapters for all nuvi units, here is a link to one For your battery it will not be able to be replaced by you the user, I only recommend replacing it through an authorized Garmin repair center.

Hope this helps!

My garmin c550 battery is dead and it still work while plugged in car power adapter - I need to reset it as its showing "memory full . All the instructions says that i need to switch off power and...

Try unlplugging GPS.
Hold power and bottom right corner.
Then plugging back in whilst holding buttons/screen.
Though you will probably have to get some new batteries for it soon.

The filter is probably blocked.

It is inside the base of the machine.

Take out the filter and clean it and also clean out the filter well as that can also hold quite a bit of debris.

Will not turn on

It is possible that the internal battery has discharged, and is unable to recharge due to a blown fuse inside the cigar lighter plug or a blown fuse in the car's fuse block for the cigar lighter outlet.

  1. Unscrew and remove the silver or black, round end piece.
  2. fileservlet?date=1&kb=%7b6b85cfa0-194d-11dc-44cd-000000000000%7d&id=%7b6e53bea0-6874-11dd-436f-000000000000%7d&ext=jpg
  3. Remove the fuse (glass and sliver cylinder) and replace with a new fuse.
  4. Ensure that the silver tip is placed in the end piece. Screw on the end piece.

Consult your car's owner's manual for locating the fuse block in the car. Both fuses must be good.

If you're unable to power up the c500 outside of the car (running on internal battery) your c550's internal battery may no longer be able to accept a charge. This will require a battery replacement - or use with a cigar adapter only. You may have to return the GPS to Garmin for a battery replacement - but there are some third party battery providers for some Garmin GPS units. If one is available for the c550, you may save enough money to make going the third party route worthwhile.

Please rate this replay if helpful - good luck!

Nuvi 760 will not take charge

I don't know which of the three ways you're trying to charge - car cradle, via USB cable to a computer or via accessory AC adapter. An 18 month old 760 should still have a good battery.

If you are using your car cradle to charge consistently, use one of the other methods and allow the 760 to charge for 8 hours. Use of the car cradle can cause the 760 to stop taking a charge after a while, and switching to one of the other methods should "refresh" the internal battery. Since the AC adapter wasn't included in the box, the USB cable method is likely your only other choice. While connected to your computer, you should download & update the 760's firmware. It's fast and free - and could solve other potential issues. Get the WebUpdater software direct from Garmin.

It is also possible that the fuse in the cigar lighter plug has opened. Disassemble the the plug to check for and replace a blown fuse.

If unable to get the 760 to accept a charge, you might need to replace the battery. There are several sources for batteries - but a free call to Garmin Support should be your first move.

Please rate this reply and good luck!

Turn on your garmin out of the car, connect to a PC via USB cable and see if the battery indicator goes away. If it does then the USB to PC cable is working and charging the unit. To test the car adapter, you can unscrew the tip of the plug to examine the fuse. Most Garmin car charger units have a light on them that ilimunates when you plug it in and turn the ignition. It could be that the plug is just loose in the socket. The picture shows the unit running on battery. If you plug in the usb cable and this indicator goes away, then it should be charging.

My GPS won't turn on.

I had this issue also. When I got it out of the box, it had maybe 30 minutes of playtime without a charge before the battery went low. I used the USB it came with and found plugging it into my laptop AND desktop does absolutely nothing; even though the states the USB can be used as a charger on the PC.

It's been less than 8 hours since I've had it, and I have not gotten a chance to use the car adapter to charge it... I have a DC/AC unit inside my house which I am using to charge the unit and it works fine (incase you dont know what a DC/AC adapter is; its pretty much a lighter adapter that plugs into the wall).

With my migraine starter experience with charging and powering on; I have read on 100's of Magellan 3250 reviews that cold tempratures cause these issues.

Other possible causes:
Battery is 100% dead = leave it in your car charging (HIDE UNDER THE SEAT!)

If the USB port plugged in charging in the car; if it is still not working, make sure that the FM part is also plugged in. I found that my GPS does not charge with just the USB end plugged... At least for me, it will only charge with BOTH ports plugged....

I hoped my novel helped... If it didn't; return your Magellan, and buy a GARMIN GPS. I have a Garmin that I bought for my hubby, and 2 years later, has never once experienced any issues.

Charging unit with AC adapter

I have a 100v A/C power / charger unit for my garmin C340 GPS that I use to charge my Garmin's battery every day. I can use thj adapter to run the GPS, or just turn it off and let it charge the GPS. But it connects dirctly to the Garmin GPS unit, not to the cradle like the Cigarrette lighter unit does. .

The car charger worked fine in my car, but if it doesn't work for you, you can always charge it using the USB cable with your computer.
