HI,

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

Your car adapter wiring might be faulty.. Green light shows it is receiving power from your cig socket but there isn't any power from the adapter to the plug to your gps..

Try this, it worked for me
Turn off phone
Remove battery
Wait 10 seconds
Plug in charger
Insert battery
Turn on phone

• 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.
  

Hit the small reset button on back,I used a toothpick

Make sure that the kindle is fully charged. Plug your kindle into the wall charger, a yellow light will light up. When the yellow light turns green, your kindle is fully charged. Then try turning on your device. If the device still does not turn on, hold the power switch for 15 seconds, this will reboot the device.

do a hard reset....remove charger>remove peripherals>remove battery> press and hold the power button for about 30secs, while batt and charger is removed> then plug in the charger only and turn ON!

Please vote, thanks!

the ram could be the problem
is it the right size ?

Could be a loose contact at the connection between the wire and at the gps unit.

Think the green light must be on at the charger port and also on the gps unit.

This green light can be found near the power button on the gps unit.
