ottocast A2Air Pro Wireless Android Auto Adapter 2023 Upgrade car electronics accessory

SKU CH-61RS-Y38AD

Converts factory wired Android Auto to wireless using a USB adapter with 5 GHz Wi-Fi and a smart control button

  • Product typeRearview Monitor
  • Converts factory wired Android Auto to wireless operation
  • Simple two-step setup via USB port and Bluetooth
  • 5 GHz Wi-Fi delivers nearly twice the speed
  • Smart button enables quick disconnect, update or factory reset
  • Compatible with Android 11 and above vehicles

What This Adapter Does

The Ottocast A2Air Pro adds wireless Android Auto to vehicles that already support the wired version. It plugs into the car USB or USB C port and pairs with a phone over Bluetooth. Drivers running Android 11 or later can access navigation, calls and music without a cable. Compatible brands include Audi, Mercedes-Benz and Chevrolet models with factory wired Android Auto.

Daily Connection Experience

A 5 GHz Wi-Fi link delivers roughly twice the speed of the older standard for smoother map rendering and streaming. The compact dongle stays inserted in the port, so there is no repeated plugging and unplugging. A built-in smart button lets you disconnect, trigger a firmware update or restore factory settings without touching the phone. Setup follows two steps: insert the adapter, then pair the phone via Bluetooth.

Upgrading From a Wired Setup

This device replaces the physical USB cable required for standard Android Auto. The jump is worthwhile when you want to keep the phone in a pocket or bag while driving. It does not add Android Auto to cars that lack the factory feature, nor does it work with Android versions below 11. Buyers needing wireless Apple CarPlay or support for older Android releases will need a different solution.
