Although Apple does not provide any option to choose their preferred Maps app, users have found a way to bypass this constraint. There are two solutions for this problem, for both jailbroken iOS devices and non-jailbroken ones. Obviously, the jailbroken solution is a little better, but for non-jailbroken phones, it’s still good because you can use Google Maps with Siri pretty easily, so you can have the flexibility that you want.
How to use Google Maps with Siri on non-jailbroken devices
If you haven’t jailbroken your device yet, then this simple trick will help you use Google Maps instead of Apple Maps to find directions via Siri. This is very simple and does not require you to install anything on your device or modify any settings. For this to work, when you open Siri to ask for directions to any place, just add at the end of your question “via transit,” and it will open in Google Maps instead of Apple Maps. So, when asking for the nearest 5-star restaurant, just ask Siri: “Show me where is the nearest 5-star restaurant via transit” and Google Maps will open with directions.
Using Google Maps as Default Maps app on Jailbroken devices
As you must have guessed, there is a simpler and better way to do this, without the need to say anything else to Siri like before. The solution comes in the form of an app, which can be downloaded for free from the Cydia Store. The app is called MapsOpener, and you only have to download and install the app, and that’s it. Next time when you open an address, it will bring up Google Maps. That’s right; it works not just with Siri but from anywhere! MapsOpener looks like a great solution for this problem, but users have reported an issue with it: for some reason, it will not accurately pinpoint the address automatically when showing it on the map, but this is a minor inconvenience, and we hope it will get fixed in the next update. By using these two methods, you will be able to open any address and get directions on your iPhone without the need to use Apple’s half baked maps and go with a more reliable and better mapping service: Google Maps.
