Portable CarPlay Screen
A standalone 7-inch touchscreen with wireless CarPlay, mount, and speaker. Works in any car, adds a modern display, and is easy to move between vehicles.
Check priceWireless CarPlay Adapter
A small dongle that plugs into your car's USB port, enabling wireless CarPlay on a factory wired-only system. Keeps your original screen and controls.
Check priceIf your car lacks CarPlay entirely, a portable screen is the clear winner: it adds a modern display and wireless CarPlay for less than a new head unit. If your car already has wired CarPlay, a wireless adapter is cheaper and keeps your factory look. Choose based on whether you need a new screen or just wireless convenience.

Quick questions
Will a portable CarPlay screen work in any car?
Yes, most portable CarPlay screens are universal. They connect to your iPhone wirelessly and power through a 12V cigarette lighter socket. You mount them on the dashboard or windshield. They do not need to interface with your car's existing infotainment system, so they work in almost any vehicle from the last couple of decades.
Can a wireless adapter make my car wireless if it only has wired CarPlay?
Yes, that is exactly what these adapters do. They plug into a USB port in your car and create a Wi-Fi network that your iPhone connects to, bypassing the need for a cable. You still use your factory screen and controls. However, your car must already support wired CarPlay; the adapter cannot add CarPlay to a car that doesn't have it.
Which option has better sound quality?
A wireless adapter generally provides better sound because it uses your car's existing stereo system and speakers. A portable screen often has a small built-in speaker, which can sound tinny. Many portable screens offer FM transmitter or AUX output to use your car's speakers, but that can reduce audio quality slightly. If sound is your priority, the adapter is the better choice.
