Navman F10 brought this unit for my daughter for Christmas. It switched on now it wont, we put it in the car to charge it and it still wont turn on. She hasn't even had a chance to use it yet.

Do a factory reset

• Turn the Navman off by holding the power button in the upper left corner of the device until the screen goes blank.
  
• Plug the unit into its charger using the USB port on the bottom of the unit. The battery indicator light next to the power switch should turn orange, indicating that the device is charging. Once the light has turned green the charge is complete. If the light does not turn on, verify that the car charger is plugged into a working outlet.
  

Have you tried another charger? its likely charger fault or gps internal short circuit. does gps unit switch on at all?

Hope i helped you.

Apparently, according to the Navman helpdesk you have to open NavDesk and from the menu, go to Tools and then Recover Keys .
I tried this on my S80 and I got an error, (E000050) which I was then told I had to send the unit back for repairs. This is my worst purchase ever. I'm on my third unit and have had nothing but trouble.

These sockets are on sale if you google enough. Ebay seller totalviews for example. Check its the right socket and be prepared for very small presise soldering. when you open the case, take great care not to break/dismantle the rocker switch that protrudes as it has minute elements in it. If charging is a problem but the socket appears sound,m check the plug that goes into it and ensure the springs go in and out to hold it in place.F4therchristmas

check the battery switch on the back. you will need a pen. Mine does the same thing. I believe this switch has to be set to ON for it to work. At least mine wont turn on unless the switch is turned on.

RECENTLY I DID PRETTY MUCH THE SAME THING
SO HERE IS WHAT I DID :
" I TURNED IT ON AND HIT THE HARD RESET AND THEN LEFT IT ON TILL ALL P[OWER WENT AWAY FROM UNIT
SECOND I HAD TO DOWNLOAN A NEW VERSION FOR MY UNIT ; MEANING MAP
THEN I TOOK THE BATTERY OUT AND AND PLUGED IN MY USB CORD AND IT TOOK IT
I PUT MY BATTERY IN AND CHARGED OVER NIGHT AND WELL IT SEEMS LIKE A LOT TO DO BUT FROM WHAT I UNDERSTAND MY DRIVER GOT BOOTED OFF THE UNIT AND ANOTHER DRIVER FOR A MODEL WAS ATTACHED
HOW I DONT KNOW BUT MY UNIT WORKS NOW FOR THE LAST 4 MONTHS NO PROBLEMS

HOPE THIS HELPS YOU OUT RICHARD FROM CHICAGO

maybe there is a flat or stuffed lithium battery or battery charging circuit in the pin 570.
fix:
leave unit to charge for 24 h
if the battery still dosnt charge because it is over discharged, then you may be able to push some charge in it after the battery is unplugged, after opening the case, and removing the circuit board

Hold down on/off button till screen clears,this should reset navman F10 .Turn back on and it should be working normally.this worked on mine.
