Carplay audio stops working
Hello, I have an Iphone 7 plus running iOS 11.3 I use carplay in my 2018 Subaru Legacy Limited. I find it often stops playing audio for calls for no apparent reason that I can notice. The car still shows carplay connected, however suddenly the audio will disappear. Yesterday for example I made and completed a call no problem, then after finishing that call I tried to make another using siri and started the call however when the other party answered the audio stopped working even the call connected, as soon as I unplug the cable the bluetooth in the car takes over and it works over the bluetooth. However if I plug the phone back in again no audio. It seems the only thing that resets it is if I stop and shut off the car and reboot the phone. Yet it was working fine minutes earlier... I am running latest version of iOS Needless to say this is very frustrating. Not sure what to try????? However working in sales I use my phone a lot in the car and want to be able to use carplay.
Thanks
