Anyone know of an app or method to get turn by turn directions of a customized route? Google has "My Maps" where I can create/save a custom route. I saw there is an app "My Pin" for $5 in the app store to view the custom route, but it doesn't have turn by turn navigation. I'm trying to take a convoluted route home from work with lots of turns to avoid some construction - google maps, apple maps, and waze all take me right through it. I want to save the route I came up with and have turn by turn navigation until I learn all the steps.
