I bought one of these cables (http://eshop.macsales.com/item/Newer Technology/AUTO12VUSBB/) to plug into the usb and aux port in the center console of my 08 BMW 328i. It works great to play music, the problem is charging. I would say about 1 out of every 10 times I plug it in, the phone charges. The rest of the time I get this "This accessory is not made to work with the iPhone" error message.
Anyone know any solutions?
