Garmin dit qu'il y a 3 cause possibles;
Wrong USB Connector
Make sure you have the right charger. Garmin will only work with a Garmin charger. You may have accidentally picked up a blackberry charger or the wrong charger.
Charger itself no onger good
If GPS is not picking up the charger , the charger may no longer be good. Trying using a new or different charger for the GPS.
Mini USB Port Bent/ Loose
If GPS has been dropped USB port could be damaged and could be why the GPS does not pick up the charger. A good way to conclude that the port is damaged is visually look at the port and see if it looks damaged. If by visual it is hard to determine connect the GPS to a USB port charger and then connect it to a computer. If computer recognizes the USB device than the port is fine, but if computer does not recognize the USB device than try to connect another device and see if the computer picks up that device, if computer does pick up other device than the port on the GPS may be damaged.
Peut être est-ce le chargeur voiture qui ne fonctionne plus correctement.
