Replace garmin streetpilot c550 battery - Garmin StreetPilot c550 GPS Receiver

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. Remove the fuse (glass and sliver cylinder) and replace with a new fuse.
3. 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!

OK, THANKS, THE MOST LIKELY PROBLEM HERE IS THE BATTERY IS DEFECTIVE.

There are replacement batteries available. Don't post in all caps please it is frowned upon.

There is no factory default unlock PIN code. You will need to take the unit back to your security location and it will automatically unlock.

http://www.tramsoft.ch/downloads/garmin/streetpilot-c550_owners-manual.pdf page 29 & page 30 discuss the 2 options for reset/restore.. one clears all saved data (i.e. favorites) & the other resets the system. I'd also suggest connecting the usb cord to ur pc & GPS , then use the update software, This can resolve any issues you may be experiencing.

To perform a master reset on the StreetPilot c5xx series:

1. Power the StreetPilot off (ensure that it is not connected to external power)
2. Touch-and-hold your finger in the lower right corner of the Touchscreen
3. Power the StreetPilot on
4. Continue to hold your finger there until "Erase all user date?" appears
5. Remover finger from the Touchscreen
6. Touch "Yes"

Please rate the solution....

Thank you

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.
