I loaded the Scenic app on my iPhone 8 last fall, but Hurricane Michael ruined fall riding for me...we are now back in our home after 6 months of repairs. So the plan now is to ride the MABDR this fall with a friend. Has anyone used the Scenic app for riding BDRs, I am concerned about cell phone reception...maybe I should not be? I have loaded the MABDR map into the Scenic program, but again, have not been able to use it or "play" with the program, so I will be a total newbie to it. Any advice or suggestions are appreciated! Want to know if loading the MABDR maps into Scenic on the iPhone will do the trick, or if I need a dedicated GPS device?
