My USB is not working in the center console. 2012 cts coupe. The Cadillac dealership is telling me i need to buy a new cable. One end has a USB with a 3.5mm jack and the other end is a chager connection for an Iphone 4. In addition they said I need to go to Best Buy and buy another cable that has an Iphone 4 connector on one end and the lighting style connector (for any new apple products in the last two years or so) on the other end. Is this really what i have to do if I want to charge my phone with the console USB?
