When using iOS 6.1.3, I can connect iPhone 4/5 to JVC KW-AV50 car stereo system using cable (30 pins / lightning). After upgrade to iOS 7, those iPhones can not connect to the car stereo. I am using original cable. Is there any suggestion or work around?
On iOS 6.1.3 this can be done without any problem. I have an iPhone 4 that was working perfectly for this function using iOS 6.1.3. After upgraded to iOS 7 / 7.0.2, the iPhone does not show any error on the screen.
iOS 7.0.2, IPhone 4, iPhone 5, iPhone 5S
