What is blocking my cars access to messages

[NMatt]

I have an Xperia XZ2 running Android 10 and I cannot access text messages on my car without having to restart my phone. Everything else (calls, contacts, media) connects and reconnects perfectly everytime but messages will not reconnect unless I restarty phone in the car. There is obviously something that blocks the phone connecting messages that runs later in the start up process but I have no idea what. My wife has exactly the same phone but no issue connecting to the car. Please can someone help with this issue

Hi Mustang7757. It's not an AA issue, it's a problem with the basic Bluetooth connection.

Hello
If you are doing AA wireless that's done by Bluetooth so it could be interfering

Ok, so AA is wired. I have removed app permissions on AA but the problem was still there, I could try uninstalling the updates (can't fully uninstall as it's a system app on my phone) and see what happens

OK, I have now tried everything except factory reset and no joy. Regardless thanks for all your help and advice, it was much appreciated
