Charging from docking
I upgraded to IOS7 a week or so ago now, not sure if that is relevant. I've got an iPhone 4s.
I've got an in car charger wired up to my stereo and a docking station that I use to charge my iPhone. In the middle of the night last night it just started going through cycles of charging and not charging and eventually said that the device is not supported. This morning I get the same thing in my car when I plug my phone in.
I've been using both these devices to charge my phone for the last 20 months so no idea what has suddenly caused this issue?
Is this an IOS upgrade thing or has something bizarre triggered this behaviour?
