Portable CarPlay and Android Auto screens

A portable CarPlay screen gives a car without CarPlay a touch screen for Apple CarPlay and Android Auto, without taking the dashboard apart. It sits on a mount on the dashboard or windscreen, runs from the 12V socket and sends the sound to the car speakers through an AUX cable or an FM transmitter, or plays it from its own speaker.

How a portable screen works

Your phone runs Apple CarPlay or Android Auto and the screen shows it, so maps, music, calls and messages come from your phone. The screen needs power from the 12V socket. The sound has three routes: an AUX cable into the car stereo, the screen's FM transmitter tuned to a free radio frequency, or the small speaker in the screen itself.

What you need

  • An iPhone or an Android phone. Apple says Siri must be turned on for CarPlay. Google lists Android 11 or higher for Android Auto, and a phone with 5 GHz WiFi for wireless use.
  • A 12V socket. Most cars have one. If yours is also used for a dash cam, a twin socket adapter helps.
  • A way to get the sound in. AUX gives the clearest sound. FM works in any car with a radio.

Fitting and the law

Fit the screen where it does not block your view of the road, and keep it away from airbag covers. Regulation 109 of the Road Vehicles (Construction and Use) Regulations 1986 means a screen the driver can see may show navigation, vehicle information or camera views of the road, but not films or other video while you drive.

Frequently asked questions

Does a portable CarPlay screen work in any car?

It works in most cars with a 12V socket, because it does not connect to the car's own systems. For sound through the car speakers you need an AUX input or an FM radio. Without either, the screen plays sound through its own speaker.

Can I watch films on a portable CarPlay screen?

Not while driving if you can see the screen. UK law only allows a screen in the driver's view to show information such as navigation, the state of the vehicle or a view of the road. CarPlay and Android Auto block video apps while the car is moving anyway.

Does it need mobile data?

The screen itself does not, but your phone does for live maps, streaming and messages. Google lists an active data plan as a requirement for Android Auto.
