Accessory not supported by iPhone
I have updated to iOS 10.3 on my iPhone 7 and my Lightning to 3.5mm/charging adaptor brings up the message in the title. It works for 1-2 min then stops with the message. Message is - This accessory is not supported by this iPhone
I use this in my car, it has Bluetooth for phone only and a phono input for music. As I also use the phone as my sat nav I need to have it charging while playing music. The only way to do this is with an adaptor that Apple do not make.
This set-up worked without issue with the previous OS.
I have 2 different adaptors and both have the same problem.
Anyone else seen this and is there a way around it?
Is there a supported way of charging the iPhone 7 at the same time as using the phono output?
Help!!!!!!!!!!!!
iPhone 7, iOS 10.3
