I obviously need to read up more on Sync 3. But apparently it looks like you can download native apps directly to it? One being Waze. Is this so and it’s independent from the phone? Meaning it can run without a phone connected? Just haven’t found out how to do it yet if so.
No, that's not exactly how it works. Ford has these connected apps that will show an interface on your infotainment screen, but all the process is still occurring on your phone. The principle is pretty similar to Apple Carplay and Android Auto...except it doesn't seem to work that well.
I've used the "Ford + Alexa" app with mixed success. Pandora didn't seem to want to work at all. I would have tried out Waze, but it's only available with iPhones, not android, currently.
I don't think Ford is going to do much with apps/features that use wfi instead of tethering (through bluetooth/USB) to your phone. I don't think there's that many people willing to pay for wifi just for the vehicle. It's sort of catch-22 though, since wifi isn't worth it if your vehicle can't do anything with it. Automakers are starting to work more with Google/Apple/Amazon to have better features though, so I do think the day will come soon.
I think the biggest issue is going to be what should and shouldn't be allowed with distracted drivers though. Voice control helps a lot, but you're still going to be limited in what you can do while driving.
