Garmin Nuvi 750 no sound

Under tools/settings/language check to make sure you have a voice with "TTS" after it, it means Text To Speech. Make sure one of those are selected and see if it helps.

Let me first start by saying that for the $$ I paid for this thing I think it is really screwed up that so many people are having the exact same problem and I truly hope Garmin fixes the glitch. Now - on to the fix..... Before getting started, you should test my theory to see if the reason you no longer have sound was the same reason as I had. Turn the unit on and ensure all the setting indicate that FM transmitter is OFF and volume is not muted. Go to the volume adjustment screen and while adjusting the volume up and down you should apply pressure to the back left side of the unit with your fingers. I found the sweet spot to be about 1/4 distance down from the top and 1/4 distance from the left of the unit. Now, while pushing in at this location on the back of the unit with your left hand pointer and middle fingers, click the volume buttons up and down with your thumbs and if you hear sound... then it's time for the SIMPLE repair!!!

There are 2 small torx screws located on the back of the device down at the bottom. I didn't have a torx bit this small but I did have an allen key that worked. take out the 2 screws and open the back plate, don't be scared. Once open you will see 2 sets of wires connecting the back plate to the main board, one is the power cable coming from the battery which is affixed to the inside of the back cover, and also the speaker wire. I had plenty of room to perform my fix without any need to disconnect these wires, just be sure to pop it open gently as to not damage the wires but trust me - you will have plenty of room to work with. On the mainboard side of the device you will see a square chip-looking thing mounted onto a metal plate which protects the mainboard. All I did was put a glob of hot glue onto this chip. The glob should sit about 1/4 of an inch high. Let the glue dry. Place the back cover back in place and screw it back together. Done. If you don't have a hot glue gun then by all means feel free to use anything that is roughly 1/4 inch in width such as a folded up piece of paper or perhaps or whatever else you want to use. If your's was like mine then you are set to go and this problem should not rear it's VERY ugly head again.

    I just used this fix today, 3/11/11, to repair my Garmin 750. It works perfectly now. I will forward this suggestion to the Garmin Product Support Specialist, who asked me to send in my Garmin to be repaired for $99. Thanks, joeeisenberg, for your helpful advice!

  • JDS300 Jun 08, 2012

    Brilliant instructions. I did not have a glue gun, so I substituted two small adhesive felt patches (the kind you place behind a picture frame to avoid scratching the walls). The good news is that my Garmin recovered its voice. The bad news is that it will not stay on--hopefully, just need to recharge the battery. Thanks for the great information and helpful instructions.

I have a NUVI 750 and the voice directions are breaking up. I know that the weather effects this, but this is getting worse. What can I do?


Hello, this possibly isn't a weather issue. All the voice combinations are stored locally on the local memory so their is no voice transmitted to GPS as in case of cell phone.

The issue is 'Text-to-speech' technology. Through in-built modules, it trys mimicing reading the english text as human's do and the sound is sometimes not natural. Its recognized as 'stuttering'

To isolate the issue, you can just select other language in the settings that is not TTS. It won't read the street names for you but you should receive a clean voice such as 'Take a left turn in 300 feet'

If you haven't registered your unit with Garmin, I suggest do it now at garmin.com. Then try for getting a latest software fix at the following location

Hope this helps.

Screen froze and it won't turn off


Hmmm. tricky. It'll eventually run flat but connect it to the computer and use Garmin WebUpdater (free download from Garmin) to check the software version - it may reinstall the software.

No Voice (sound) even when volume is at 100%


What sounds are you expecting? GPS only throws direction when there is going to be a turn ahead. most of the time it is silent.

If it is MP3 Player, there are 2 volume settings, Master and Audio check both are non-zero

Also check (if it has FM transmitter), you might have diverted the sound to an FM Station. You should see that option as well in the volume setting.

SYSTEM SOFTWARE MISSING!! on display - the maps just needed update - now the 'missing system software' is displayed ,, I thought it was the map updates needed to be updateed so I went to the Garmin website...


I had the same problem with my nuvi 200. I contacted Garmin via phone (toll-free number) and the tech was very helpful. He said that this happened when I was updating because the program was interrupted while the update was in process. The problem is because I needed the USB drivers for updating--don't know how they got deleted but once he sent me an email with the instructions and attached zip file to reinstall the drivers and reset machine, everything is good to go again.

NO SOUND ON GARMIN 750


I had the same problem. I fixed it by going to settings, then to language, and then entering American English into the Voice category. Hope this helps.
