I have a 2014 Mazda CX-5 and the USB port no longer works. I have 2 iPod classics and 2 nano-pods. I purchased new apple cables because the dealer checked it and said it was my cable, not the USB port. None of the four work in the car. The USB icon on the radio will not light up, no connection. It is definitely a bad USB port but the dealer keeps insisting it is my devices!We just got a 2015 CX-5 Touring with Nav, 2wd and I thought the USB would charge my phone or IPAD. It does not, in fact it isn't highlighted on the dash. I'm not sure it works. Or is it just for playing direct to the radio? Bluetooth works great. I think when we first got it, it would charge the phone. I can wiggle it and it will seem to charge for a second. I may have been seeing things. Anyone else with this problem? Other than that I really love the car.
