Wireless CarPlay Adapters: What to Know Before You Buy

Does your car only have wired CarPlay? Here is how wireless CarPlay adapters work, what to check before buying one and how to get the best connection.

Many cars support CarPlay only with a cable. A wireless CarPlay adapter is a small device that plugs into the car’s USB port and lets your iPhone connect without a cable. It is also one of the easiest ways to use screen mirroring apps like Carplay Pro in a car with wired CarPlay.

How does an adapter work?

The adapter plugs into the USB port your car uses for CarPlay. Your iPhone pairs with the adapter over Bluetooth and then streams over Wi-Fi. To the car, it looks just like an iPhone connected with a cable.

What to check before you buy

1. Your car must support wired CarPlay

Adapters convert wired CarPlay into wireless CarPlay. If your car has no CarPlay at all, an adapter will not add it.

2. Firmware updates

Choose an adapter whose maker publishes firmware updates. Updates often fix connection drops and add support for new iOS versions.

3. Boot time

Some adapters take longer to connect after you start the car. Reviews from owners of the same car model are the best guide.

4. Power and port

Some cars have more than one USB port, and only one supports CarPlay. Use that one. A few adapters need extra power and come with a Y-cable.

Getting the best connection

  • Keep the adapter close to the port and avoid covering it.
  • Update the adapter’s firmware and your iOS version.
  • If the connection drops, forget the device in your iPhone’s Bluetooth settings and pair again.

Things nobody mentions until you own one

  • Your phone no longer charges from the cable. The cable used to charge the iPhone while you drove. Wireless CarPlay drains the battery faster than wired, so on long trips a wireless charging pad or a separate USB charger is worth having.
  • There is a short wait after starting the car. The adapter has to boot and then find the phone. Cars that cut USB power when the engine is off will make you wait each time; some cars keep power on for a while, which makes quick stops nicer.
  • A tiny delay is normal. Audio and touches travel over Wi-Fi, so they can lag slightly behind a wired connection. For music and maps you will not notice it.
  • If your car already has wireless CarPlay, you do not need one. Check the owner’s manual or try connecting without a cable before buying.

Adapters and screen mirroring

With an adapter connected, Carplay Pro can mirror your iPhone to the car screen the same way it does in a car with built-in wireless CarPlay. What you can show can vary by car model and adapter, so try your setup once while parked. Our step-by-step guide on mirroring an iPhone to the car screen picks up from here.
