20 Most Recent Garmin Nuvi 255 GPS Receiver Questions & Answers

First, a freezing problem or lock-up during boot-up has nothing to do with the LCD display. If the screens shows a graphic, such as the Garmin logo and without lines or splotches, then the screen is fine. Lock-ups during boot-up are caused by corrupted firmware or maps or a corrupted flash drive. All of which can be resolved without taking the unit apart. The battery has nothing to do with it either. If the unit locks up while connected to the car charger, then the battery is essentially being charged and not powering the unit. I can't see your board but if you pulled the ribbon out of the board, you may have damaged the locking latch that holds the ribbon in place. The locking latch is a thin white or rust-colored strip of plastic on a hinge. That hinge should be up when sliding the flex cable into the connector, then the locking latch is pushed down toward the flex cable until you hear it click. The flex cable should be secured at this point. If you have busted the locking latch off, it is game over for your Nuvi. More info on booting issues can be found here:

Try a master reset. Hold the power switch to the left and hold for 10 seconds and release. You may also have a bad USB charging port. A common problem with units with USB only connectors.

The battery status only shows up when the satnav is disconnected from the charger. Your first charge should be a continuous charge until the battery is full. This can be done by connecting it to your computer for 8 hours approximately or 4 hours to your car cigarette lighter socket or 4 hours to an, optional extra, mains charger.

There is a reset button on the 255 i on the bottom right edge as the unit faces you, and is underneath the serial number sticker. You'll either have to peel the sticker up for access or poke a hole through it. This should get you going again. I am am also attaching a link to garmin support. Let me know how you made out. Thanks for using FixYa

It should unlock automatically.
Try reconnecting your device to computer and going onto the garmin site and get the website to check for updates.
If that fails to work, give garmin a call or send an email to them.
they are normally very quick.

The 2xx series had a batch with bad batteries and they are replacing them even out of warranty , try your serial number on https://my.garmin.com/rma/recallLanding.faces. See if it is eligible for repair, if not the unit is probably pooched.

Hope this helps!

First press the speaker symbol and check that the volume is not down fully or that the mute box is not ticked. If it is press the mute box to untick it or increase the volume. Otherwise follow the instructions below.

1. Press Tools, then press Settings (or Locale on some models), then press Language. You will see a bar for Voice. Press Voice and select a different voice. If this doesn't solve the problem it's most likely because the voice file has become corrupted. To replace the corrupted file.

This problem is caused by the mini usb plug of the power cord not being fully plugged into the back of the satnav. It's a common problem on 200 series garmin satnavs. Because of the way it's made you think it's fully in but it's not. Push it in further and the problem will be solved.

If the lighter socket is working ok then it may be the fuse in the charger plug that's gone. It can be replaced by unscrewing the silver ring at the end of the plug and removing the fuse. A replacement fuse should be available from garmin dealers.
