Is there anyway to improve the brightness of the display? Set to 100%, and tried several different themes, but in daylight, simply can't see without shielding the display.

Hi @JeffH_Canada
Your VIA 1525 is the equivalent of a START52 in Europe, serial number starting with XQ. TomTom gives different names to the same products depending on the marketing or purchase area.
For this type of device if the power supply is not strong enough or if you use a non-compatible car charger the screen darkens.
Do not use the USB port of your car if you have one (only 500 mAh like the USB port of a PC) or a third-party car charger. Many are not compatible with Tomtom devices. Use the cable and the car charger supplied by TomTom (1200 mAh).
Look at here "US User manual" VIA1525 = Start52:

Personally I use a third-party car charger which works correctly for my TomTom devices. But I was well aware of the risk of incompatibility of my purchase.
Depending on where you have installed your TomTom device, you may need a sun visor. I bought this on Amazon:
- Above the car radio and the on-board computer I don't need it.
- On the windscreen at the bottom left in summer it is necessary depending on the car used.

Hi
@JeffH_Canada
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 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.....

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'

Thank you. Will check the power supply and see if that helps. Not using the car USB though.1

This has done the trick! Thank you!
But it begs the question... why? Many cars only have one power port and And since the tom-tom GPS is meant to be used in a car it makes me wonder why it wouldn’t be made to be compatible with an in car USB port.
At any rate, problem solved!0 -
