Restart device for Bluetooth to connect

[JRS1]

Hi,

First time sony owner here. 

I'm having an issue with my car bluetooth connection and my AL Priority parking sensor system. 

Both run off bluetooth, but i need to restart my phone each time i get in the car for my AL Priority to connect. This happens with both of my cars (both have the same AL Priority system installed). Once in a  while my cars bluetooth (cadillac ATS-V) will not connect till i restart the phone as well. 

Anyone else seeing bluetooth issues like this? This worked fine with my OnePlus 1, Oneplus 3, and Pixel.

Thanks in advance,

Jon

Just to add to this, it might have something to do with Android auto. If I keep my phone disconnected from the wired AA connection my Bluetooth seems to connect the next time I get in the car. 

Only tested with one car so far, but twice today I've successfully connected to both devices without having to restart my phone.

looks like i was good for a couple days without having to restart my device for bluetooth to connect. I ended up disabling all sony apps that i could. as of yesterday afternoon the problem is back.

i get in the car and unti.l i restart my phone my bluetooth with not connect to my accesory. if i restart the XZP it will connect once before i have to restart it again.
