[HowTo] XA2 Bluetooth connection to car
I've paired my Xperia XA2 with my 2013 Volvo Sensus successfully. It works pretty fine, even better than the Xperia X. Phone book, recent calls, etc. work.
The known problems when pairing the usual way still exist. It works if you make your car's Bluetooth interface visible and search for it in the phone. When you try to connect, the car will request a PIN, but the phone doesn't show one. Just enter 0000 to pair them.
