I recently had a Pioneer AVH-4200NEX installed in my car. Upon connect my iPhone 6S to the lightening cable, carplay does not show up. I made sure I connected to USB1; the stereo shows it being connected to USB1. Everything else works fine with the stereo, but the main reason I bought it, Carplay, doesn't work.
iPhone 6s, iOS 9.3.4
Hi
It may help to follow the steps here, under "Get help":
Not sure if this will help, as you said you made sure you checked if it was in USB 1. I pulled out the entire headset, and while the unit was telling me it was in USB 1, and the phone was charging, when I looked on the rear of the unit, I was in USB 2.
A quick way to check this if you're not eager to pull the unit out, have someone w/ Android Auto connect to your stereo. If it opens after you tell the unit "other" for smartphones, the USB connection leads to USB 2 in the rear.
Worth a try, worked for me.
