Internal battery won't charge
Common issue. Steps to troubleshoot/solve:
1. Pull off face, press reset tab.
2. If unit wont turn on or if turns off immediately, connect to home computer using mini usb on side of gps (any usb cord that fits will do). This will charge the internal gps battery, which is discharged.
3. You will not be able to see the gps charge indicator while the usb cord is plugged into the unit. To check charge level, disconnect it, turn it on, and note the large "battery" icon.
4 Do you have a dead internal battery? If the gps holds a charge from your computer usb port, you don't.
5. If you have a dead battery, Google DIY replacement. With some soldering it can done for $15 total.
6. If you don't have a dead battery, the issue is charging from the cigarette lighter socket. Your car socket may have blown a fuse (check car manual). Your charger unit may have blown a fuse (unscrew the tip, check fuse inside). Also, some car sockets don't work when the ignition is off. Test yours.
7. There is a good chance the connection of the charger wire to the gps cradle is the problem. Fiddle with that. Replacement cradles are available for the c340 at about $25.
8. If your unit is not charging from the cradle/socket, buy a 12v usb cord. Plug into socket and into usb port of the gps. This is a workaround or alternative to buying a new cradle.
9. IMPORTANT: observe the "battery" icon while driving, esp. if you have doubts about charging. Basically, if you can see the icon, you're not connected to an outside (car or computer) power source. That is, if you can see the battery-charge indication, it means your battery is currently discharging and unless you get another power source to work it will be dead in a few hours.
