Nuvi 750 tuns of as soon as it comes on

Charge it overnight with a high power usb charger, 2A or greater. If it works properly the next day, the issue is with your vehicle charger. If it is still not working, reposition the ribbon cable that the battery connects to.

Hello :

Resetting your GPS could solve the problem .

Here is how to reset your NUVI :

1:Turn the Nuvi on.

2:Touch the tools icon on the main screen. The tools icon is represented by a wrench surrounded by a blue circle.


3:Touch the "Settings" icon which appears as a wrench.

4:Push the "Restore" button at the bottom of the screen. A confirmation message will appear asking to confirm restoring the Nuvi to factory settings. Push yes to restore the factory settings
............................................................................................
Try this for hard reset .

Turn off Garmin device. Press down on bottom right corner of the touchscreen [ Don't let go ] , and then power on the GPS unit. You should be prompted whether do you really want to erase all user data, or asked if do you really want to start up in maintenance mode. Press “Yes” to reset (warning: all data will be erased and lost, so backup before proceeding) or enter maintenance mode.

PLEASE DON'T FORGET TO RATE !

Try resetting the unit. The procedure can be found here:

Time for a new battery. If you talk to garmin they will want to replace the entire unit. You can buy a battery for about $23 and do it yourself.
Here is on place that sells them but I would also search for others to compare prices and specs.

Hi Jessica,

Move the on/off power switch to the left and hold it there for at least 30 seconds and see if it comes back on. I know there was a bug in a firmware version that makes the unit "bricked" after a certain date. The only way to fix it if the reset didn't fix it is to disconnect the battery inside, reboot the unit and install the firmware fix.

maybe a factory reset - but connect to computer and try to back up your stuff since it will erase it all.
