Question about Garmin nuvi 780 GPS

1 Answer

Our Garmin Nuvi 780 is new and worked fine the first 2 times we used it. However, it will not give us the voice instructions now and we can't find instructions to reset or correct the problem. The online help advises we go to tools, settings, audio but there is no audio choice in this category. Please help as we are leaving today for a 10 hour drive. Thank you.

You can check "settings", then look for the picture of "lips". This is the language area. I always just select American English. You can set whatever you like. Also, check your volume setting. Just touch the "speaker" on the main screen and up will come the volume. Increase to a level you like. I use 90 percent.

I purchased 3 nuvi 780 models about a year ago. One for me and one each for my children. Not long after we started using them the sound quit on 2 of them. Neither the FM or internal speaker will work on...

The most common cause of this problem is that the voice files become corrupted and need to be replaced. To replace them:
  • Download and install WEBUPDATER to your computer from
  • Connect your satnav to your computer with the mini USB lead and run the WEBUPDATER program.
    Webupdater will find any updates to your software that are available. Select all and install them to your satnav. When the update is complete it will then find optional updates including VOICES. Select a few of the English speaking voices and they will be downloaded to your satnav. After the download is completed SAFELY disconnect your satnav from your computer and restart it.
  • Press TOOLS
  • Press SETTINGS
  • Press LANGUAGE
    This brings you to a screen with 3 items; VOICE, TEXT LANGUAGE and KEYBOARD
  • Press VOICE and select one of the English speaking voices you downloaded.
I hope this solves your problem.

Touch tools > settings > language > voice.

Voice- changes the language for voice promts.
Languages noted with a persons name are (tts)
text to speak voices.

which have an extensive vocabulary and pronounce
the street names as you approach turns.

The pre-recoreded voices (those without a persons name)
have a limited vocabulary and (do not speak names of locations or streets)

Text language- change all on-screen text to the selected language,
changing the text language does not change the language of user entered data
or map data, such as street names.

Keyboard- select the keyboard for your language,
you can also change the keyboard language mode from any keyboard
by touching the mode button

Adjusting the volume levels
From the "menu" page touch "volume"
to adjust the volume.
To adjust the volume levels for the media player
and the navigation prompts,
please click.

Tools > settings > Volume > Restore
Restore will, restore to origional volume levels.

You should be good now
