Wont turn on
Try this: Slide and HOLD the power switch into the ON position for 10 seconds or until it turns on - which ever happens first. This forces a reset / reboot of the GPS. It does NOT delete any data.
If that doesn't work, the battery may be discharged. Recharge by connecting to your computer's USB port with a USB cable, or with the AC adapter (if yours came with one) for 8 hours. Do not use your car's cigar lighter or power point to do this (it won't work). Turn on as normal or failing that, use the slide & hold method detailed above. After starting up with the slide & hold method successfully, subsequent power up operation can be done in the normal manner. You can use the slide & hold method any time the GPS fails to start up normally.
One power up method or the other should allow the GPS to start if the battery still has a useful life. If it does not power up, it is likely that the battery is no longer capable of holding a charge. In this case, you may purchase a battery and attempt to replace it yourself (this is a fairly involved process), or you can contact Garmin Tech Support to arrange for a flat-rate repair.
I hope this helps & good luck!

Heres what to do:
- Connect to computer using USB cable
- Flip up antenna and hit reset button.
- The unit should power up.
- Then put unit on wall charge to get a full charge.
That should do it if not call 1-800 800 1020.

I called Garmin and they gave me a simple procedure to fix this problem. Turn the nuvi off. Plug the nuvi into a mini-usb cable connected to your PC. Wait until the nuvi screen displays a picture a nuvi connected to a PC. Disconnect the nuvi and it's fixed.
It lasted a few months before the keyboard started losing letters again. I'm going to call again and see if I can't get a permanant solution.

SOURCE: Won't stay on
Have you installed anything lately? Do you have any sd card installed? Usually this is the cause for it to crash. There is a reset on the bottom of the nuvi, when it locks up blank, press the reset button and see what happens...

If the unit indicates "software/firmware missing", then you can only try to re-install firmware by running WebUpdater again. If it doesn't work, then the unit has to be sent to service to have it re-flashed.
