In Apple’s Maps app, which debuted in iOS 6, you’ve always been able to set the volume of the voiced directions, choose whether you want to use mile or kilometer units, and set your Map Labels to Always English or not.
In iOS 7 beta, however, you’re now able to set your preferred direction type. Here’s how.
Launch your Settings app with a tap, and scroll down to the Maps icon. Tap that, and then you’ll see the preferences for the Maps app in the right hand column if you’re on an iPad, or on the preferences screen if you’re on an iPhone or iPod touch running iOS 7 beta.
Scroll to the bottom, just under the Map Labels section, and tap on your preferred directions type: Driving or Walking. Now, when you type an address into the Maps app, you’ll automatically get the type of directions you want. So, if you’re a walker by nature, you’ll always get the best walking route. If, on the other hand, you live in a place where driving is the only option, then you’ll get the best driving directions.
No options for Transit yet, so we have yet to figure out how that will work once iOS 7 is out of beta this fall. So far, the Transit button in Maps itself does the same thing it did in iOS 6: it lets you choose from apps that support transit directions from the App Store or your own iOS device..
