Nuvi 255w has no voice navigation


Do you hear beeps when you press a function on the screen? If so, this rules out a blown speaker. If you don't hear any beeps, your speaker may be blown out.

Is the sound muted? Is the sound level set to 0? Check by pressing the speaker icon at the main menu.

Would you like to erase the phonebook entries on your Garmin Nuvi 255W, left over from when you bluetooth paired with your cell phone?

I can help you delete the phone numbers on your Garmin Nuvi 255W.

The phone numbers transferred to your Nuvi are only supposed to be available when your phone is paired to your cell phone. Changing the entry on your phone should allow that entry to show up changed the next time it is paired with the Nuvi. Sometimes, a bluetooth mix up causes entries to be duplicated or entries' phone numbers to get repeated.

To correct this, I recommend backing up your favorites, clearing all user data (this hard reset will remove the phonebook info from your nuvi), and then updating your Nuvi' firmware to make sure the nuvi and cell phone bluetooth process runs as smoothly as possible in the future.

Follow these three steps to take to get your Nuvi 255W running like new:

  1. Back up your Favorites.
  2. Perform a Hard Reset.
  3. Download and then run Garmin 255W WebUpdater to replace its firmware / system software.

I hope that helps.

No sound on the 255W


Hi Judy, Most likely, the speaker has failed (open voice coil). I've repaired many Nuvi's with this problem. More information can be found here:

No Sound or Garbled Sound on a Nuvi Series GPS


I've seen many posts of "No Sound" or "Garbled Sound" for the Garmin Nuvi Series. This is a common problem with the Nuvi.

In order to troubleshoot this problem, we need to determine if it's a hardware or software issue or a setting issue.

No Sound:

1. Try the obvious. Is your volume setting turned up?

2. Is the sound muted with the mute button?

3. If your Nuvi has a FM transmitter, is it selected to "FM" or "Speaker"? The "FM" setting will mute the internal speaker. Setting it to "Speaker" will send sound to the speaker.

Garbled Sound:

1. Does the sound seem to be better at lower volume settings?

If you still can't hear audio or if the sound is garbled, then we now have to determine if the internal speaker is defective. The easiest way to do this is:

1. Plug a set of headphones into the headphone jack. Now try listening to the sound. Listen for the touchscreen beeps, MP3 audio, voice directions, etc. Try adjusting the volume using the headphones. If you can hear sound through the headphones and it's clear and not garbled, then your internal speaker is defective.

The headphone jack is not only a jack but it's also a switch. When you plug in your headphones, the audio amplifier of your Nuvi is switched from the internal speaker to the headphone jack. When you unplug the headphones, your Nuvi's audio amplifier is reconnected to the internal speaker.

Now, if you can't hear audio through either the internal speaker or the headphone jack, you may have a different problem.

1. The internal audio amplifier (hardware) is defective.
2. There is a software problem. You could try resetting your Nuvi with the reset button or perform a factory reset. The software problem is more likely if you can hear MP3 audio or touch screen beeps but not speech.

The internal speaker has a voice coil. The voice coil is nothing more than a thin piece of long wire, wrapped around a magnet, numerous times. If you can't hear any sound, it is very likely that this coil is "open"; meaning that the wire has broken inside. If the sound is garbled, this is an indication that the speaker is mechanically defective and not reproducing the sound as it should. The speaker has a "diaphram" that moves in and out as it reproduces sound. If the diaphram has been damaged, it can't move in or out like it should and reproduce the sound clearly. There is also a possiblity that the voice coil has shorted windings, meaning that instead of it being a long piece of wire, it's now shorted to its adjacent windings and is electrically shorter now. Again, this can impact the reproduction of sound.

So, why did your speaker go bad?

1. It's possible it was defect in the manufacturing process and failed prematurely.
2. You might have had the volume up too high. I recommend using the lowest volume level possible. High volume levels put greater stress on the diaphram and may overheat the voice coil.
3. A speaker is an electro-mechanical device. It's subject to being damaged if you happen to drop or jar your Nuvi and/or operate it outside of its normal operating parameters.

What's the Next Step?

If your Nuvi is under warranty, I strongly suggest that you contact the manufacturer and tell them what happened. Tell them all of the steps you have gone through to confirm that the speaker is defective. If the warranty is still in effect, they should repair or replace your Nuvi.

If your Nuvi is out of warranty, try calling the manufacturer anyway. You have nothing to lose. Maybe they will replace it anyway.

If you have no sucess with the manufacturer, you will need to take your Nuvi to someone who is qualified in repairing your Nuvi.

I hope this tip has been helpful to you. Feel free to contact me if you have further questions or require further assistance with this problem.

Best wishes,
- Jim

Just went to use my garmin 255w and screen is all garbled with a black mark and weird marks on screen. Is there anything I can do. Thanks


Looks like the screen is broken. Did it fall down? Did you carry it in a backpack and forgot about it?
If you turn it on and press with your finger on the screen. Does the mark move?
