Cannot Play Music From IPhone 6 Plus While Connected Source As IPod

When I plug in my iPhone 6 Plus to the USB and connect as iPod, I cannot play music I've selected through my vehicles infotainment system. I have a 2013 Honda Accord. All previous versions of iOS have worked almost flawlessly in this car and my last one. However, since purchasing the iPhone 6 Plus, I have had nothing but problems with using my car as an iPod connecting to the audio system. Sometimes it just says "loading"... this flashes back and forth, but it never loads. Other times, it will load, and I can browse my music and podcasts.

However, when I select a song, it will not begin playing. I can go to the "Now Playing" section of my Music app and see that the song I had selected has been chosen, but I have to click the play button on my iPhone to make it play. I have Siri Eyes free, and it construes to work. However, Siri seem to be getting less useful all the time. This whole issue has really got me upset. I paid $1,000 for this phone. It is supposed to Just Work.

I assume it is a software issue; I wish the would get around to fixing it. I, personally, find this unacceptable. This is a core function of the phone. I don't really care about health apps... Apple Pay is cool... but they should not do a single thing that messes up the core functions of the phone. Being able to connect to my car and listen to music is why I paid Apple's ridiculous price to upgrade to 128 GB or RAM. This is like upgrading the software and not being able to make phone calls for 3 months until they finally release some random software update.
