Permanently preventing sleep mode VIA 1525M

I have a TomTom VIA 1525M - is there a way to permanently prevent it from going into sleep mode ? Is there a way to set it so it never goes into sleep mode ?

    Battery Savings settings-->Check option to keep device on when external power lost

    Thank you for responding. I have changed the setting as you suggested but haven't tested it out.

    Are you using a USB port in your vehicle?
    As the USB ports in your vehicle provides only 0.5Amps and are for data transfer and not supplying power; whereas your device should have 1.2Amps to run AND charge the battery. With a vehicle USB port the reduced power means that the device tries to save it's power requirements by dimming the screen, reducing power to the SIM thus dropping traffic info, and, as you have found out, it then sleeps.
    Try plugging the original cable into the original cigarette lighter charger, does it then keep sleeping?
