TOMTOM GO51 - Backlight gets weaker when attached to power

HenrikJensen

Can anyone tell me why the backlight turns down to about 75% when I connect my TOMTOM GO 51 to USB power?
The backlight gets brighter again when I disconnect power.

I have choosed 100% brightnes in daylight mode.
All updates have been done. (Programversion 21.200.0003.311)

Thanks in advance for your help :-)

Thanks guys
It's a cable thing. I didn't use the original TomTom cable.
Everything is working perfectly now.

Have a great day
All the best

Hi @HenrikJensen
Welcome to the community!
Are you charging it from a stand alone USB port or using the USB connection from a Cigarette lighter adapter?

Regards,
Vikram.

Thank you for replying.

I am charging from a 2amp USB outlet on my motorbike.

Hi
@HenrikJensen
Welcome to the site....
The Previous NAV4 and Latest Wi-Fi Connected 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 parties 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'

Stay Safe... ATB YFM
