Don’t Have Apple CarPlay? This $50 Upgrade Could Save You From Buying a New Car

Apple CarPlay has become an increasingly popular feature for drivers, bringing navigation, music, messages and other iPhone functions directly to the dashboard. But what happens if your car doesn't support it?

You may not need to replace your vehicle—or spend hundreds of dollars on a complicated infotainment retrofit.

Portable CarPlay screens offer a relatively inexpensive way to add the feature to older vehicles. According to Engadget, many of these displays cost less than $50, while even higher-end models priced around $150 can still be significantly cheaper than upgrading a car's built-in system.

The devices typically sit on the dashboard and connect to an iPhone, essentially providing a standalone display for CarPlay. They aren't as seamlessly integrated as factory-installed systems, but they can deliver the core features drivers want without requiring a new vehicle.

What should you look for?

Screen size is one of the first considerations. Portable models generally range from about 6 to 11 inches, with larger displays offering more screen real estate but potentially becoming more distracting or difficult to position.

Resolution also matters. A screen with at least 1280x720 resolution can provide a considerably better experience for reading navigation instructions, icons and other information.

Audio connectivity is another important factor. Since built-in speakers on many inexpensive portable screens aren't particularly impressive, support for AUX, Bluetooth or FM transmission can make a significant difference.

Drivers should also make sure the device supports wireless CarPlay if they don't want to connect their iPhone with a cable every time they get in the car.

Some screens offer more than CarPlay

Portable displays are increasingly becoming multifunctional accessories. Some models include built-in dash cameras with microSD recording, while others support rear cameras that can add parking assistance to older vehicles.

Some also run Android, allowing users to install and use apps without relying entirely on an iPhone.

The biggest drawback is aesthetics. A portable screen won't have the same clean, factory-integrated appearance as a built-in infotainment system, and cheaper models can suffer from poor displays or unstable mounts.

Still, for drivers with older vehicles, the value proposition is difficult to ignore. A relatively inexpensive portable display can bring modern smartphone connectivity to a car that otherwise lacks it—without the cost and hassle of replacing the vehicle or installing an expensive factory-style system.
