New to Mountain Biking, I have been using my Apple Watch to track basic data using the included cycling app, it maps the ride, mileage, elevation, time, calories, heart rate, basics that are pretty good considering it's included with the watch. It would be nice to be able to plan a route and be notified if I'm off route, directions etc, can that be done on an Apple Watch or iPhone? I'm a little hesitant to put an iPhone on my bike (do people actual put phones on mountain bikes?).

Thanks
