You got lucky. I also bought the wireless dongle and my phone was not compatible. Only the latest phones are but the requirements are nowhere to be found. I also tried a simple phone with android Go but turns out Go does not support android auto at all. This is also not said anywhere on android auto page. Now I have another ohone and a cable and it does mostly work but the voice assistant (like the most important feature when driving) is buggy, the screen gets all messed up from time to time, support for it in apps is still not great and of course it all goes through google so bye bye privacy. Of course it’s better than the infotainment systems that all the car brands had because it’s does support more apps and the big car display is better than phone holder but overall it still sucks. A truly open standard that would let phones just display stuff on the car’s screen and get input from it would be so much better but of course there’s no hope for it.
