How do I stop my Start 62 screen from dimming when I plug it into power.

Every time my device turns on while plugged into power the screen dims. When I unplug the power the screen brightens up. I have the brightness already set to 100% but it is still too dim for daylight use. It is set for daytime use when it does this. Can anyone please help?

    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.
    Try plugging the original cable into the original cigarette lighter charger, does it then keep dimming?

    I am having the same problem......I lost the original car charger [a techy kid made away with it]......so i tried the cell phone charger and got the same results as actionman .....I could plug the house charger in all night and have the tom tom light properly for five or six hours while plugged into the car..........then go dim.....

    I have a new tom tom charger on the way..........for the next trip.........

    Thanks for the reassurance I'm sure that is what the problem is.......

    Hi
    @2laner

    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

    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)... A dashboard USB port can also fool a NAV4 Device into entering 'Updating Mode' and display the Connected to your Computer splash screen
    (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 (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
    _______________________________________

    As a test...
    Try using the Tomtom supplied cable and Tomtom supplied Power Adapter

    The Charger Adaptor and USB Cable supplied by Tomtom WILL run and charge the device at the same time

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

    No, I was using the cigarette lighter socket in my car and also does exactly the same thing when I plug into my computer for updating. I've since contacted Tom Tom and they're sending me a replacement. Thank you for all the replies though.

    You say you were using the cigarette lighter socket... but you haven't said which Type/Make Power Adapter you were using ???
