Just got a new 3rd party (Kenwood) deck for the car. CarPlay (on an iPhone 6) is giving issues. It didn't work, then I switched lightning cables, it worked (2 different phones) now it won't work (either phone). I've done the steps such as restarting the deck, plugging in and out, rebooting the phone (including holding down both buttons until the Apple logo reappears), closing all apps, etc. I also deleted the deck profile from my phone. Now the phone doesn't even see the car deck. I got the deck as an open box item from Crutchfield (who has awesome installation service, but crap CarPlay support help), so it could be the deck (maybe) but before going through the return and reinstall process, does anyone know other hot points to check? One question I have -- could the USB cable be at fault? I had to buy a USB cable extender to get a port from the deck into the car, and then I plug the lightening cable into that. Do USB cables have to be chipped in any way? Just trying to figure out what the issue could be.
