I have some very interesting news. I sold my CX-5 recently, and I sold off a lot of stuff I had bought for it. The last thing I sold were my wheels and snow tires to a guy I work with who just bought a 2014 CX-5 Sport. As we were talking about the car, I asked if he had the iPod issue, figuring he would of course say yes. But he was just confused and asked what iPod issue? I explained and he said nope, mine starts right where I left off every time. I was floored of course and told him he was the only one I had ever heard of that didn't have the issue.
I thought about it later and wondered if he was using Bluetooth. Next time I saw him, I asked, and he said no, he uses the USB cable with his iPod. He also said he double checked after talking to me and said it for sure starts right where he left off every time. So I then thought maybe it is his iPod and asked to see it. I can't say for sure, but it looked like one of these iPod Classics. He said he didn't know the model, but that someone gave it to him last year for Christmas, so it must have fairly new software.
Anyway, thought I 'd share. If I still had the car I would be buying one of these iPods for sure just to see if it worked.
CX-5 Sport (base model) uses a different, basic H/U not affected by "high tech" issues.
