Hi,

There could be two (2) possible reasons for the Nuvi 770 to mute:

  • inadvertently muted;
  • firmware glitch.
If the unit was accidentally muted, go to Menu, touch Volume to adjust Master Volume; or Tools, Settings, Volume, Restore.

If the unit has a system glitch, cycle ON/OFF or "Slide the Power Key to the Left and hold for 8 seconds. Turn the Nuvi back on.

If all else fails, you may need to reload the firmware or seek the assistance of Garmin.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

Try to reset the nuvi and also check your settings that you have voice enabled / or notifications.

    Turn the nuvi ON. Slide the power key to the left and hold it for about 10 seconds documents say 8 seconds, then the nuvi back on. 


    Let me know how it goes.

I want to leave Michigan and go to Toronto, Ontario, Canada. I am unable to program this into my Garmin nuvi 1300. Any suggestions?


You will need to enter an address in Toronto for it to be able to route. Try "1 Yonge Street, Toronto, Ontario". That will take you to downtown Toronto.

Hello,

nuvis can be very particular about which 3rd party accessories they will take, try obtaining a garmin 12v power cable this should fix your problem.

Hope this helps!

Sincerely, you will not be able to get a free voice download for your garmin nuvi, except if you have some other voices on the latest updates and downloads. Reason being that, garmin nuvi tries ti make profit after creating the device that works for your navigation. So I will advice you buy one, from garmin nuvi website as it is available there.

My Garmin nuvi 200W has had a battery recall and replaced by Garmin. It powers up OK and locates OK but hangs after approx 0.5-1 hours. I cannotr even turn it off without pressing reset. I have updated the...


Send it back to Garmin. The fault may be coincidental, but unless you fancy buying a replacement model it's worth seeing what Garmin have to say. It should only have been a straightforward battery swap, but if the technician forgot to wear an earthing strap it's entirely possible that a component suffered static discharge damage.

I've been holding back from sending my nuvi 770 in as the battery seems fine and I've often had problems with shoddy recall work on digital cameras and similar devices in the past.

Our Garmin Nuvi was working until we stopped the car.


I've had this happen on three successive Nuvi 760's which I sent back, the serial numbers all suggested that they came from the same production batch..

Eventually I got a Nuvi 770 which has been fine. I understand that it's not a problem with the basic design as the 770 is really just a 760 with more memory, but it's probably a fault with a batch of components used during a production run.

This is not a DIY repair; contact Garmin even if your unit is out of warranty as they might offer a goodwill repair for free or at reduced cost.

Worked for me but not sure why, I had the same problem of freezing when updating Bluetooth firmware on a Nuvi 770. I chose to reset all user data (press lower tight hand of touch screen while powering on) and next reboot it updated firmware sucesfully. No idea why this worked.
