The navigator batteries are probably flat. To recharge the internal lithium battery connect the navigator to the car cigarette lighter socket by the adapter that comes with the navigator (mains power unit is not included and the navigator cannot be charged by connecting it to the PC via USB). It is always best to fully charge the battery for before using it for the first time. Caution: do not cancel the "Cities" and "Mobile Navigator" files since this may cause a navigation malfunction and invalidate the warranty.
