so i went through all of my settings and could not find anything, but i plugged in some headphones to charge them through the USB and system says "device not supported" which is fine because i am looking to just charge. I clear the screen but it keeps coming back every 5 seconds. tried multiple USB outlets in truck and keep getting message reoccurring. Really irritating!!!! Why can't i clear message once and that be suffice, don't understand why it has to keep coming back every 5 seconds. Any ideas?
