Make sure any apps you want to run on SYNC are already running on the phone. If they aren't running on the phone, they won't show up on screen.

Yeah then the "detour" function is probably more similar to what you're looking for, but that's only an additional route on top of the fastest/shortest/eco routes. Another thing you could do is set the route, start driving the one you want with the prompts muted, then unmute them once it updates the route to the one you wanted.

While on the topic of navigation, I agree with the about it's very annoying. Another question though, is there a way to choose from multiple routes when a destination is selected? The only option I see is detour. All of my old navigation systems gave me a list of like 7 or 8 different routes for me to choose from. It would be nice to have this here.

Go into the Navigation settings and disable the option to automatically select the fastest route. You'll get 3 route options when you set a route then.
