Brightness of the display

Hi, I have a problem with the display of my TomTom GO 520 (WiFi). Whenever I connect the navigator to the external power supply, the brightness of the display decreases. As soon as I unplug the power, the brightness increases. I believe it should work the other way around. Do I need to change anything in the settings?

    Hi
    @lollo386
    Welcome to the site....
    If you mean when updating ??? It's supposed to dim the screen to conserve power...
    A PC USB Port usually only supply 500mAmp (0.5Amp)
    ___________________________

    The Previous NAV4 and Latest (NAV5 WiFi) devices are quite power hungry and can go into "Power saving mode" if not supplied with enough power
    Are you using the Tomtom supplied cable and Tomtom supplied Power Adapter
    The Charger Adapter and USB Cable supplied by Tomtom WILL run and charge the device at the same time

    Many 3rd party Mismatched Charger Adapters won't run and charge the device at the same time
    See... It's not simply a power thing.....

    _____________________________________

    When the device is In use they are designed to be always connected to a power supply
    The Tomtom supplied Power Adapter is rated at 5Volts 1.2Amps
    Even after you have recharged the device externally via a mains' charger, when in use in the vehicle, they will still require being connected to a Tomtom supplied Power Adapter (Or a proven suitable 3rd party Power adapter)

    (1)... Do NOT attach them to a dashboard USB port in your vehicle as they normally only supply 500mAmp (0.5Amp) and are for data transfer and not supplying power: See... Note (1) & (2)

    (2)... Using a NONE Tomtom 3rd party underpowered or a mismatched cigarette lighter charger can cause the device to go into Power Saving Mode: See... Note (1)

    (3)... On the Models with a built-in SIM, the reduction of power to the SIM can cause the dropping of the traffic info: Note (3)

    Note (1)... At an (Undisclosed) percentage of battery discharge, the device will try to save its power requirements by dimming the screen and eventually powers off the device... Devices with a built-in SIM Card may also lose Live Traffic services
    Note (2)... A dashboard USB port can also fool a NAV4 Device into entering 'Updating Mode' and display the Connected to your Computer splash screen
    Note (3)... I tried connecting my Tomtom GO 6200 to my Cars USB port, checked the connection status it reports 'Connected over USB' --> 'GPRS (SIM) Disconnected'

    Hi, thank you for your reply.
    Unfortunately I am forced to use a magnetic cable since the micro sim connector of my support (on my previous model go 500) broke using the supplied cable and forced me to buy a new support. I will try to use the supplied cable and see if the screen mantain the brightness.
    unfortunatelly the link you posted me does not woerk
    Thanks for the support

    sorry for my english
