This same thing happened on my nuvi 780 and I just had to go into settings and re-select English as the language and it started working just fine.

Garmin nuvi 780 says no data found and no maps


Sounds like the data on your SD card is corrupt. If you know somebody else with the same unit and model try their SD card. If not them you are most like going to have to buy a new SD card and install the maps and operating system onto the new card. Should be instructions on you install Cd assuming you have them.

Garmani nuvi 780 freezes on "updating bluetooth firmware 0%" when turned on


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.

Garmin nuvi 780-when recharging the battery should the user know when it is complete and how long should it take?


Hello skatecat,

The Garmin Nuvi 780 GPS receiver should take about four hours to fully charge. You can review the charge status by checking the battery icon in the top corner of the GPS's menu page.

Best Regards,
Ken

Garmin nuvi won't turn on


folks, the garmins have an on-board battery that needs to be powered up (at least occasionally) via the usb port - like from your computer. just using the dc car power cord does nothing for this battery. i've had this exact same problem on both my 760 and 780 nuvi units. fixed it using the usb charge. seems to run down differently for all the various nuvi models. my regular charge will hold for 7 hours on my old 660, my 760 and 780 work about 5 hours. my 'power up' failed on the 660 after 10 months with no internal battery charge, but the 7xx models only took about 5-6 months to 'fail.' hope this helps. jack b :-) in midland, tx usa
