Some edited thoughts on my settings with AAWireless Config 1.8.2 that may help someone. This version of the app works best with OTA firmware version 1.3.0. Which should be available soon for all versions of the AAWireless device. It may also be used with OTA firmware 1.2.x, but we have identified some problems that are fixed in OTA firmware 1.3.0. Update when you get the chance.

The 1.8.x version of the app introduces the Start / Stop option.

I have a 10.25 Hyundai head unit. I think that the Wireless Projection function of this unit is the same for KIA and Genesis 10.25 inch head units. This head unit first appeared in 2019 Korean model years and is very flexible when used with with AAWireless.

Here are the settings in the AAWireless Connect app version 1.8.2 that I use and what also works with my head unit.

USB Mode I use MTP, but Direct works as well. The head unit responds a bit faster with MTP.

Passthrough I have it turned off. The head unit works with Passthrough turned on, but DPI, Remove tap restriction, Disable Audio Sink, AutoVideo Focus and Developer mode cannot be processed by AAWireless when on. When on the exact encrypted data conversation is transmitted between your phone and the head unit. When off, AAWireless joins the conversation to inject those Experimental Features.

Force 2.4Ghz I have it turned off. The 5Ghz channel used is 40. This feature will turn off 5Ghz Wi-Fi in favor of 2.4Ghz Wi-Fi on channel 1.

Start / Stop I have this turned on. What it is designed for is those vehicles that keep the USB port powered on while the ignition is off. My Hyundai keeps the USB port powered for several minutes after I turn off the car and leave vehicle. With this turned off, my phone won't connect to my home network.

WiFi connect timeout I now leave this at the default 20 seconds. For a couple of months after the initial conversion to Android 11, my Samsung Galaxy S20 FE 5G phone would not connect to AAWireless on the first try. It would always connect on the second try. Samsung fixed their problem with a subsequent update. But while this was a problem, reducing the WiFi connect timeout to 5 seconds really helped.

Adjust audio timestamp I have it turned off. The head unit also works with it turned on. Turn this on if you notice things out of sync. With OTA firmware 1.3.0, enabling this option will help with certain Volkswagen Auto Group (VAG) head units that crash when playing audio.

Change DPI I use 130 to see more of the map. Lower numbers make the area of the map shown larger but the text will be smaller. The number 0 will restore the default used by your phone, head unit combination.

On my head unit, using the number 103 will put Android Auto into wide mode with map and media side by side. But it is still only displayed in the left portion of the screen, and much of the text is too small for me to read.

Remove tap restriction I turn this on, it helps me with my on phone music collection. The head unit works with this off. Some other head units will not update your GPS map position properly with this option on.

Disable Audio Sink I have this turned off. Turning this on will make your phone use something else for audio. In my case it is the phone's speaker.

Auto video focus I have this turned on. This option tells my Infotainment system to switch to Android Auto when AAWireless connects. I don't have to navigate through the screens to get Android Auto up where I can see it.

Developer Mode I have this turned off. The head unit works with this turned on. An app update will be needed to correct the text. Frankly, I am not sure what is enabled by setting this on, but Emil is sure some of you will know.

I often use the app with the AAWireless device plugged into a USB A power source, like a power supply or a charging port in your vehicle. The Android Auto traffic going through the device can make app less responsive.

When an OTA is available, it is better to download the OTA with the AAWireless device powered off and your phone on WiFi. Once the download has completed, turn on AAWireless, link to it again and upload the OTA to the device.

I use a large microSD card in my phone (Samsung Galaxy S20 FE 5G) to store my music collection. I play the music with Rocket Music Player. Works very well under Android Auto.
