Hey there @Ed29010,
I just copied this and made it a post, so we can discuss it here:)
Anyone having issues with Android Auto Wireless? Since reinstalling my Kenwood DDX9905s in my pickup I have been unable to stay connected to Android Auto via wifi for more than a few seconds. This morning I discovered the culprit is Blokada. When Blokada is off AA works normally but, once restarted the wifi connection is dropped. I’m using the AdGuard setting in DNS.
