I have a 2018 with Syn3, and an iPhone. Got the truck Memorial Day weekend. Was frustrated at first cuz only a few apps worked. Suddenly without me doing anything (that I know of) about 2 weeks ago Waze started working. Still frustrated that you have to plug the phone into the USB rather than just Bluetooth. Can't "download" an app, but seems to work if you plug in, open an app, there are apps that will start working. I only tried it because I was seeing the new Ford commercials on TV showing Waze on the in car systems. Wish I could tell you how to do it. It just happened for me.
