Can I adjust the brightness manually?

Yes. The H1 features automatic brightness adjustment, which adapts to ambient light conditions. You can also manually adjust brightness levels in the settings to ensure comfortable visibility at night.

Does it have a speed warning or alarm?

Yes. You can set a custom overspeed alarm. When your speed exceeds the preset limit, the device will alert you to help promote safer driving.

Does the display show direction?

Yes. The H1 includes a compass function that displays driving direction (N / S / E / W).
