Commonly Asked Questions

Will it work on iPhone 15/16 with USB-C?

Through our testing, USB-C iPhone does not support both fast charge and data at the same time. It will pioritize fast charge over data, thus disconnecting carplay when higher power source is detected.

Which AndroidAuto wireless adapter will work?

We have had positive report on AAWireless which has USB-C input. No USB-A wireless adapter has been tested or report working from our customers.

Why I got slow charge or no charge at all?

Try to rotate the power USB-C head by 180 degree at the adapter. Also make sure that you are using USB-C to USB-C for all cables. USB-A will not work in this application.
