Latest version of ios 9.2.1 is not compatible with my car audio system

Hello

Since I upgraded my iPhone 5 ios to 9.2.1 my touchscreen on the audio system fly of my Toyota Prius no more answers when my iPhone 5 is connected to the USB port.  Toyota told me that I must try to downgrade to the previous version of the ios.  It's very annoying.

Can someone tell me what to do and how to solve this problem.

Thanks in advance for any help.

You can not downgrade iOS, Apple does not support. I would check with Toyota once again to see if they have an upgrade of your system. Only they can tell you if they support iOS 9.2.1 for their system.
