Phone problems Loudspeaker

[AC Question]

Hi after using bluetooth in my car no problems.As soon as I turn car off and walk away there is no sound (ringing dialling keyboard etc) only way to here somebody talking is thru load speaker.Turning phone off gets normal functions but as soon as I get back into my car than get back out issue returns.Phone is Sony Xperia Z1 Compact 4.4.2 car is Subaru WRX 2014.I don't think it has anything to do with the car.

Have you tried turning Bluetooth off after getting out of your car?
