Hello all, I am needing assistance on how to get mixtrax working on this head unit. I had a xbs head unit that could play mixtrax with just a connected iPod via usb. With the 4100nex, it’s not happening. I’ve switched USB ports used 3 different cables, and nothing. I even got a iPod touch in attempt to put mixtrax through there. I loaded 256gb of music and it sat for a week and couldn’t even get through 1gb of music. I can’t help but wonder if my head unit had been hacked or fixed just to sell. Can I continue pushing or just look for an avic nex model that’s plug and play. I need this feature
