AAWireless TWO+ vs Ottocast U2AIR Pro Wireless CarPlay Adapter
Which should you buy? Our verdict on both, pulled from our full The Best Wireless CarPlay Adapters: 4 Compared (and One to Skip) comparison.
The AAWireless TWO+ covers both phone platforms, makes switching drivers a button press and pairs with an app that handles updates and troubleshooting. The Ottocast U2AIR Pro does one job, wireless CarPlay for iPhone, at a lower price with automatic reconnection to the last phone used.
AAWireless TWO+
Buy itA CarPlay and Android Auto adapter with a pairing and switching button, a companion app and a two-year warranty.
- Handles wireless CarPlay and wireless Android Auto, so one adapter covers an iPhone and an Android phone in the same car.
- A multifunctional button pairs a new phone, switches to the next phone or puts the adapter in standby, and AAWireless says it can pair an unlimited number of phones.
- The AAWireless app handles setup, firmware updates, button configuration and troubleshooting, and the adapter carries a two-year warranty.
- Wireless CarPlay needs an iPhone X or newer, and wireless Android Auto needs Android 11 or higher.
- The box lists only a USB-C to USB-A cable, so a car with a USB-C CarPlay port needs a separate cable.
- It costs more than the Ottocast if you only ever use an iPhone.
Ottocast U2AIR Pro Wireless CarPlay Adapter
Buy itA low-cost, iPhone-only wireless CarPlay adapter that reconnects automatically and updates over the air.
- Ottocast says it remembers your iPhone and reconnects automatically when you start the car.

- Ottocast's package graphic shows both USB-C to USB-A and USB-C to USB-C cables, plus a sticky pad for mounting.
- iPhone and CarPlay only, with no Android Auto support.
- Switching phones means disconnecting CarPlay on the current phone or turning off its Bluetooth or Wi-Fi.
- Ottocast lists Sony aftermarket head units as not compatible and asks Mitsubishi owners to check before ordering.
