Latest version of ios 9.2.1 is not compatible with my car audio system
Hi,
Since I upgraded my iPhone 5S ios to 9.2.1, my touch screen on the Fly audio system of my Toyota Prius not longer responds when my iPhone 5S is connected to the USB. Toyota told me that I have to try to downgrade back to the previous version of ios. This is very annoying.
Can anyone tell me what to do and how to fix this.
Thanks in advance for any help.
