Review (5/5): Getting Apple CarPlay actually is just as simple as popping out the old and inserting the new!
I have a 2016 F-150 XLT with Sync 3 and the large 8" touchscreen. I've been using android phones and the android auto feature since I bought the truck. I just recently switched back to iPhone and after doing some research found that all you need to do to get CarPlay is switch out the USB module. I've seen these for as little as $40 but most on Amazon are about $60. Installation was simple. I just used a thin flathead screwdriver, popped out one end and used my keys to hold it open (if you don't put something in to hold the one side it will pop back in when you go to open the other side). Swapping out the connections was easy. Snapped it back in place, started up the truck, a new screen came on asking to tap ok for CarPlay and voila! I now have Apple CarPlay and it works great!.
