    Same problem here with a Nuvi 350.... Looks like Garmin has some manufacturing issues. I've e-mailed Garmin for technical support

    I have a related problem. My speaker works, but I can never hear it, too faint. Do they make external speakers for the better sound? This might also solve other issue.

  • cmillonida Dec 26, 2007

    Got mine yesterday, and at the end of the day...DEAD, No sound output through the internal speakers....every other option works, headphone jack, fm trans. But no internal. Did a reset, updated software, adjusted volume, even a reset to factory settings, and still nothing. =(

  • Nyulak Dec 29, 2007

    I have the same failure mode. Volume is set fine and audio will output to the FM transmitter, but I normally listen to my iPod, so that does me no use. I did manage to get the speaker to crackle as I removed the unit from its cradle, and I heard poor audio quality speech, but I have yet to get sound since that time.

    it appears that there is an intermittent connection, but I don't know how to open the case to troubleshoot it myself.

  • Torotno Dec 31, 2007

    I have the same problem, sometimes when I knock the device I can hear the speakers... it seems that is the wiring problem but I have no idea how to open the device to check out...

  • mr pepperman Jan 23, 2008

    Am on my third Garmin Nuvi 660, the first problem was the speakers died completely, second unit kept freezing and failed to sync with phone, my third unit every time I switch it on it goes through minutes of loading bluetooth software then phone will not work, have to switch phone on and off a couple of times then it syncs, whereas my wife has a 660 and has no problems.

     The service from Garmin was very good, just replaced the unit 'twice' but I am now out of guarantee and am rather unhappy.

  • MarkMayle Feb 27, 2008

    I am on my second Nuvi 680. On the first one the speaker would intermittently stop working (this was after about two weeks of using it). Tapping on the side would sometimes get it going. Called Garmin and they replaced it. Now on my second one the speaker sounds like it is blown (after about two weeks of use), voice is all garbled, etc. Everything else works fine. Tapping does not help on this unit. I hope I can get Garmin to pay the shipping on this one as it is getting expensive to send these back.

    the sound on the speakers on my garmin nuvi has stopped working

  • GarminNubie Apr 19, 2008

    Just received mine, charged it up, internal speakers have predominant static sound. Most of the pre-loaded MP3s and audiobooks don't play either. Just sits there in "play" mode, but wont start the track. Oddly, I was able to play (clearly) ONE of the preloaded items, but nothing else. Can press the play button to display a "pause" sign, then press again (thinking it would play), but nothing. Haven't tried the FM transmitter yet - will do so tomorrow. Sounds like this could be a common out-of-the-box problem though, eh? Do I bother trying to fix, or assume it's just a quirk? Assume I should just send back to Garmin for replacement. Thoughts?

    I lost the internal speaker on my nuvi 680 after upgrading to the
    latest software. Now only the FM transmitter works but not that

  • LAXFAN7 Jul 06, 2008

    My 660's speaker went bad too. Not sure about the 1% defect rate cited in this thread, looks like the speaker issue is bigger than that. I'll be sending mine back to Garmin for repair. While the FM option works fine when in the car, I like to use outside the car sometimes to listen to audio books so need the speaker. Otherwise, FM is the way to go!

    Bought a refurbished nuvi 660 from Circuit City. Arrived July 17th. Used it for about an hour and the internal speaker just quit mid-sentence. FM transmitter still works. Makes me wonder if this unit was originally returned to Garmin for a problem with the internal speaker. :O(

  • Moylan59 Jul 27, 2008

    My internal speakers started sounding garbled and then they just stopped. If I have the unit turned off for a long while and turn it back on it may work for awhile but then it just goes silent again. Just took a long trip with no out put. I am frustrated as this was not an inexpensive item

    Nuvi 680 and I have the same internal speaker issue. There for a while if I smacked the back, then it would come back. Now no sound at all. This happened about a year after I have had it. I assume bad solder connections to the speaker, but I haven't taken it apart to find out.

    Sound went out while using bluetooth. Have tried all the remedies on here. Nothing is working. No sound at all. Not the beeps on the touchscreens, nothing.

  • Speculist Oct 17, 2008

    My nuvi 680 voice started sounding very rough for last few weeks through its speaker, then failed entirely this week. FM transmitter voice still works fine. After reading these posts, I slapped it sharply, and the rough sound comes back for several seconds at a time, but not reliably. Sounds like a repair is needed. If out of warranty, as anyone opened up unit to better secure speaker connection? I do not see any screws. (Is it pried apart like a iPod?)

  • rjf26 Jan 23, 2009

    Same problem with my 3-year-old 350...started sounding garbled a few weeks ago and completely went out tonight. I love my garmin & use it a lot for work, so for now I'm using a little ipod speaker that plugs into the headphone jack:)

  • mmatheso Feb 09, 2009

    I have the same problem. I have reloaded the newest software and all the fixes. Sometimes after a reboot it works for a couple of minutes and then stops again.

    The FM transmitter has so much static that it isn't a viable alternative. The headset works fine but isn't really my preference while driving.

    My Nuvi 660 is just over a year old.

I think you had set to mute , your internal speaker should work. No unit are defective concerning speaker. It's less than 1% of the total of the production who has a defective speaker.

Make sure you had choice a TTS voice.

For those who think they had a problem with FM trnasmitter. Do not forget that the law in US do not permit a high power for fm transmitter. Just buy a good fm trasnmitter and you will get the signal very niceley from your GPS to the car stereo.

Apparently Garmin used a defective speaker for these units. I had the same problem and used earphones or the fm transmitter as a workaround. When the battery finally started going bad, I decided to replace it myself...I discovered that the speaker would work intermittently if I tapped on the vibrating part of the speaker. Not sure how I'm goint to get a replacement for the speaker yet.

Posted on Nov 07, 2010

  • Eco Phil Nov 13, 2010

    There is a problem with the actual speaker. I opened mine to replace the battery and discovered that the speaker would work intermittently if tapped or light pressure was placed on it. I am currently trying to find a replacement speaker. I'll post again if I have any success.


Shut the bluetooth off and make sure it is not muted.

Make sure the volume is up - The little speaker icon on the right side of the main screen. If that doesn't work, sounds like the unit might be defective...

2. down arrow once - (a picture of a speaker should appear with sound written vertically next to it)
3. Right arrow once (selects the sound menu)
4. Down arrow till you see FM transmitter (down arrow 4 times on my TV. If you don't see the FM transmitter option in the menu then upgrade your TV to the latest software (details at the end of this help file)
5. Right arrow to get into the FM transmitter menu
6. select the "FM transmitter: off" line and turn it on (FM transmitter : on)
7. Change the frequency to to one that is not used by a radio station or has interference noise (get a radio and tune it till you hear the choosh sound with no beeping or clicking from lightning - then set the tv fm transmitter to that frequency using the up and down arrow keys and enter.
8. You should here your tv sound comming through the radio even if the tv sound is off.

If you need to upgrade your tv software then:
1. format a usb stick
2. download firmware.exe from"
3. click on firmware
4. click on "Upgrade File(USB type)" and download it to your usb stick
5. when the download is complete double click on the file and extract it to the usb stick.

What is the FM radio frequency to use the Hannah Montana Wireless Microphone?

FM 99.7 works best.... However if you have a local FM station using that freq your out of luck UNLESS your handy with a Jewelers screwdriver. Calling tech support will get you a "sorry" but there is nothing we can do. So if you are one of the unlucky ones with a Local 99.7 FM station here is what you can do.

1) Find a dead spot on the FM radio band either at the very low end or high end of the range. You should hear just fuzz (white noise) on your radio. However, on many newer FM tuners if there is no station broadcast there is nothing but silence.
2) Put batteries in the microphone.
3) Get a really really tiny flat head (Jewelers)screwdriver just like the kind in those eye glass kits they sell at the grocery store.
4) Sit right in front of the radio
5) Insert the screwdriver into the tiny hole in the microphone and tune the microphone until the radio goes quiet (no fuzz sound). Or.... you can keep pressing S to hear a beat and the beat is acutally heard through the speakers.

The hole is located just to the left of the screw that you undid to get at the battery compartment, but it's off center. Inside this hole is a small tuning screw. Slowly, slowly, SLOWLY turn the screw driver until you here a change or interruption in the fuzz sound on the radio speakers. This will indicate you found a compatible frequency. Then even slower - tune back to that "notch" until you hear nothing but silence on the radio. Test it by pressing the applause button "A" or by pressing the mic "M" button and talking.

There are multiple places on the FM dial that will "work" as you tune the little screw but you should have already manually selected where (the FM freq) you want to use your mic.

Once it's working it ain't perfect. I doubt you'd do a serious performance on it, but the kids love it.
The mic quality is not top notch for sure.

Fine tune as necessary....

Everything works fine on the unit no problem until

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.

if this side of it works then the FM transmitter is faulty

Check that the sound has not been MUTED

plug the earphone into the socket to see if any sound is heard. The socket is also a switch that takes sound from internal speaker to ephone and reverse.
If no sound is hear in either FM or normal mode your unit is faulty and needs repair

Pioneer GEX-FM903XM, system works great, however it often drops out and has just static. The signal indicator is strong. I think there is a bad connection into the radio. Where should I start...

It may be possible that the FM frequency chosen during setup, is in use in your area by a strong signal from a local station. Change to another frequency and see if the situation improves.

The following is from the Operation's Manual:

FM Modulator Setting
You can adjust FM Modulator frequency and output level.
7 Frequency
If output from the FM Modulator is hard to hear due to interference from a strong broadcast
station transmission, you can switch to another frequency.
You can adjust frequency between 87.9 and 90.1MHz.
7 Level
If the output sound is too quiet, too loud or distorted, you can adjust FM Modulator output
You can adjust level between “LEVEL–1” and “LEVEL–7”.
1. Press the POWER button for 2 seconds to enter the FM Modulator Setting

2. Select the desired frequency
with the left/right arrow buttons.

3. Increase or decrease the Level
with the up/down arrows (buttons).

4. To cancel the FM Modulator Setting mode, press the POWER button again
for 2 seconds.
• After entering the FM Modulator Setting mode, if you do not perform an operation within about 8 seconds, the FM Modulator Setting is automatically canceled.

interference or static, try another frequency by repeating the process above.

No sound!

If you can hear audio through the headphone jack but not the internal speaker jack, then the speaker is bad.

This is a problem I have seen many times before. I will be posting an article soon on how to replace the internal speaker, however this is not a repair that just anyone can do.

You have to have skills in dissassembly & soldering.

No, unfortunately ther is no way to get the unit to use your car speakers. To do this, the unit would have to have an FM transmitter or be able to connect to one. It does not have this capability. Sorry.

I had the same problem with all three of my Roady XTs. I posted a video with directions for solving the problem on YouTube:

Basically, you just need to have the antenna unplugged when you power up, and push menu right away, then select. Not sure why, but it worked on all of my Roady XTs. On the oldest one I had to push menu more than once. Good luck!
