Hi All! Whenever ever I plug in my iPhone 4S into my USB port on my 2010 Traverse (LTZ if it matters), I get a "USB Power Exceeded" message display on the screen and then it does not recognize the device. It was working just the other day and then all of a sudden I get this error message. Does anyone have any experience in solving this issue or could possibly point me in the right direction? Thanks in advance for your help -I appreciate it!!!
