Please advise as to why the screen brightness during the day is getting duller, to the extent that it is almost impossible to see in direct sunlight or any reflected light, it used to be ok but has gotten worse lately, how do i correct this?

Are you connecting to a usb port in the car? If so, don't. Not enough power gets to the device that way. Use the car charger instead.

jonrun

yes it is connected via a usb port, i will the belkin higher voltage adapter that plugs into the cigarette lighter and see how that goes - I will report back, many thanks

@jonrun

If you do not have the original cigarette lighter charger, make sure that the replacement is rated at least 2.0 Amps

Hi
@jonrun
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... [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...[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.....

I have this problem too. It used to be OK but suddenly it failed to show at full brightness. My TomTom was only supplied with a USB lead not a charger. I've tried different cig plugs without success.
I remember seeing posts about this a while back where it was suggested that it was a software problem that was waiting for a fix.
At the mo I am using an mains voltage inverter via the cig plug with a mains phone charger, this is only rated at 1A so still puzzled. you help would be appreciated.

I have tried to change the outlet to a quick charge one, it appears to be a very slight improvement, but its still no as good as my other tom tom from the other car.

I have checked the display brightness = 100% Day & 15% Night, many thanks for your continued assistance

Hi
@jonrun
What is the charge level of the battery ???

The best way to check your true battery charge state
Have the device plugged into a power supply
Press and hold the on/off button until you hear a drum-roll sound, then continue to hold the on/off button Until the black and white text screen appears
The battery status is towards the bottom of the list

Battery charge level 100% (4183 mV)
