Hello, since you can connect to www.mirroid.com, this means that the dongle itself is okay. ePlease go under settings and try to see if there is an OTA update... Also, try using it on a friend's car who has a stereo with wired Android Auto.
Can you send a video showing the issue? (upload to google drive)
We're preparing a firmware update tutorial.
This forum does not allow me to inline images so I will describe in words.
The dongle S/N is CZ201201005266
OS version is 2.4.50
SW version is 2.3.63
Custom build version: alps-mp-p0.mp1-V5.273
In the settings, under upgrade, the software says "This is the latest version" and the upgrade button is grayed out.
When I connect the dongle to my Bolt, nothing happens. The dongle color blinks blue for a while (indicating that it is booting up), then goes solid blue (which I think means it has booted up but not projecting). The dongle never goes orange (which seems to indicate that it is projecting).
On the Bolt, I can go to Apps on the car screen and choose "projection" which would force Android Auto to the screen if it were up and running. However, the car then says: "Projection device not connected. Connect a supported device by USB to use this feature." which indicates that Android Auto is either not running or not talking to the car.
Also, on the dongle, USB is in "File Transfer" mode and Android Auto has all permissions on. I did not change these settings.
