Siri can help you do all kinds of things, including help you get transit directions, even if Apple Maps doesn't support them. If you've got Google Maps or another transit direction app installed, Siri is smart enough to integrate with it in most instances. Here's how:
How to get transit and walking directions with Google Maps and Siri
- Press and hold the Home button on your iPhone or iPad to activate Siri.
- Now ask Siri to give you transit directions by saying something like "Give me transit directions from Waterloo Station to Westminster." Obviously you would replace my directions with your own.
- Siri then suggests what app you'd like to use. I use Google Maps and if you are too, tap on Route. Keep in mind you must have Google Maps installed on the iPhone or iPad in question for Siri to recommend it.
- Google Maps or the transit app chosen will now launch and provide directions.
That's all there is to it. I've found this to be an easy way to bypass using Apple Maps too. If you'd rather use Google Maps with Siri, you can always just ask for transit directions every time and then just toggle between driving and walking once Google Maps launches.
