Is an Android Head Unit Legal in the UK?

Conditional

Fitting an Android touchscreen head unit is legal in the UK, but you cannot watch video on it while driving. The rules forbid a moving-image screen positioned where the driver can see it in motion, with sat-nav and reversing cameras as the exceptions.

Why?

Swapping the stereo for a big touchscreen head unit is a normal upgrade and legal to install. The restriction is about what it displays while you drive. Regulation 109 says a television or video screen must not be positioned so that any part of the moving image is visible to the driver while the vehicle is moving.

That rule has built-in exceptions for the screens that help you drive: sat-nav maps, reversing and parking cameras, and vehicle information displays are all fine. What is not fine is playing films, video or anything with moving pictures on a screen the driver can see while the car is in motion - that is an offence even if you glance rather than watch.

The unit also must not block your view out of the car or get in the way of the controls. Fit it tidily, keep video off while moving and use it for navigation and audio, and an Android head unit is road-legal.

What decides if it's legal

A screen must not show moving images visible to the driver while driving.
Sat-nav, reversing cameras and similar driving aids are allowed exceptions.
The unit must not obstruct the driver’s view or the car’s controls.
Using a screen for video in view of the driver in motion is an offence.

Does it depend on your car?

The screen rule is the same in every car. It is about what the driver can see while moving, not about the make or model the unit is fitted to.
