Any idea if I wanted to go back to cmu150_NA_70.00.100A which is the 2 file version of software, would that work? I can not get my android auto wireless to work since upgrading to 74.00.230A. I downgraded to 70.00.367A and it is still not working. I realized I was wrong when I said in a earlier post that 70.00.367A was working perfectly for me. It was actually 70.00.100A. If possible I would go back to that to see if the android auto wireless will work again. For reference I am using a AAWireless adapter to have wireless android auto in my car. If its ok to go back to that version from .367 and I can find that firmware that would be my next step in troubleshooting my connection issue.
