Garmin 750 The audio on the GPS no longer works. Just stopped working for no reason .

At some point you may have switched the unit off before it completed it's start up dance. This will wipe out the voice file more often than not.

You will need use Garmin's web updater and re-install the file for the voice you want.

the term is waypoint and these can be set up in your route from the menu screen

There is a software bug Garmin has been working on for a while. The voice file changes to none. To fix go to tools, settings voice and change to desired language. Sometimes the language files get messed uo and need reloaded from webudater, this can be obtained from www.garmin.com. The latest Garmin Software version is 4.80

There is a gps repair guide that show you how to disassemble the gps. is the audio jack loose? if so i can trick the gps into thinking that a headphone is plugged in and disable the sound. otherwise try firmware update.

Try connecting the GPS to your computer with the included USB cable. If it charges this way then you can assume that the Charger is defective.

Garmin will fix or replace a defective GPS within the first year. Go to http://www.garmin.com then click on the support tab. You can follow the menu selections to obtain warranty support.

Look under settings>language>voice. Select American English and it will work again. The same thing happened to me this week on my new Garmin 750 and I took a couple of days to figure it out. Hope this helps.

I had a similar problem on my vacation. the voice stopped working suddenly. in my case i could get it working again by reselecting the voice (american/british etc) in the language section. for some reason it had reset to blank.

but i still cannot get the text to speech to work.

Every Garmin Nuvi unit I've seen has a (loud) built-in speaker. The only demand our 250s and 265 make of the vehicle is a 12V power supply (and they'll even work without that for a while, until the battery goes flat).

Go to this url and I hope this helps. It worked for my Garmin 750.

I have found the only thing that works thus far is to click on the red phone in progress icon then go to "call options" then click transfer audio to phone, then transfer audio to nuvi. Sometimes I have to do this twice. but it works.
