I have an iPhone 5 running iOS 6.0.1. When I open the iPhone's native Maps app and tap on the "Bent Arrow" button at the top left of the screen, a new screen appears that allows the me to enter a new route or choose from a list of previously used routes. My question is, how to delete one or all of the previously entered routes in that list? I've looked in the Maps settings, swiped the entries to the right and left to bring up other options, all to no avail. I have tried searching the internet and forums for an answer but the results of all the queries refer to the Google Maps app not the iPhone's native app. The only thing I haven't tried is calling Apple or my carrier. I thought I would ask the experts first.
