Andorid car problems since today

[xzaza1001]

Hello, I do not know exactly if there is help here also German, therefore in English.

I have the Xperia 5 IV. On Saturday I connected the phone to my Golf 8 and Android Auto worked. Yesterday I did a software update on the phone and this morning Android Auto did not work anymore. The car can not connect to the phone. In the options I always tried to set to data transfer and always got the error from the phone, not possible.

I tried to uninstall Android Auto. Now I can update or disable it in the play store but can't open it.

Please help me, I drive 4 hours a day and depend on Andorid Auto.

Otherwise I will use my old phone again starting tomorrow and will try to get Sony to take it back.

Hey @xzaza1001, you can clear the phone's cached data from settings - storage - cached data then force restart your phone by holding the Power and Volume+ ant test again. 

Also what is the connection method to your car? USB cable or Bluetooth?
