Ottocast Mini Cube 3.0: wireless Android Auto made easy

Tested in a 2020 Mercedes CLS using a Samsung Galaxy S25 Ultra. It adds the convenience of wireless Android Auto while keeping excellent sound quality and familiar in-car controls.

The Ottocast Mini Cube 3.0 turns a wired Android Auto connection into a wireless one, so my phone connects without needing to plug in a cable for every journey.

Easy everyday wireless Android Auto

Once set up, Android Auto connected and worked as expected. Maps and music information appeared on the vehicle display, the steering-wheel controls continued to work, and the audio quality remained excellent.

Setup tip: after pairing your phone, check the vehicle display and complete any Android Auto prompts shown there.

What I liked

The biggest benefit is convenience. I can get into the car with my phone still in my pocket and use Android Auto without connecting a cable.

Everyday benefits

  • Wireless Android Auto without plugging in
  • Excellent sound quality
  • Maps and music information on the car display

Works with the car

  • Steering-wheel controls continued to work
  • Compact adapter does not take up much space
  • Simple to use after the initial setup

Small side note: on my Mercedes display, the Android Auto logo takes up more screen space than I would prefer. This is a minor visual point and has not affected how the adapter works.

My verdict

The Ottocast Mini Cube 3.0 gives me the convenience I wanted from wireless Android Auto while preserving excellent audio and the controls I already use in the car. For a compatible vehicle with wired Android Auto, it is a useful upgrade that makes everyday journeys easier. Check compatibility for your own car and phone before buying.
