2014 Mazda6 GT iPod connection problem
 

I am having problem with my iPod USB connection in my 2014 Mazda6 GT. My iPod works with my other cars, but not with the Mazda. I connected the USB cable but for some reason the audio does not receive the USB connection. It's a simple connection so I don't why the USB tab in the audio does not light up to allow me to touch the USB tab to play the iPod. Any suggestions? Thanks!

Note: In the Mazda 6 forum, many owners of 2014 have this issue and the dealers seemed not able to fix the software issue. Apparently, owners bought in March 2013 have this issue. I bought mine in December 2013. As of June 2014, Mazda still does not have a solution, and I understand that 2015 model owners complained about this! Mazda really should be ashamed by not able to solve the USB connection problem after over a year!
