The Simple Trick To Use Google Maps With Siri | Business Brainpower with the Human Touch | Scoop.it
For all her faults, Siri is a useful companion. Sometimes. But she defaults to Apple Maps. Thankfully it's rather simple to trick Siri into giving you directions with Google Maps instead. No jailbreak required.

As shown in the following video, instead of saying, “Take me to the nearest Best Buy,” tell Siri “Take me to the nearest Best Buy via transit.” Those two little extra words prompts Siri to open a screen which displays transit apps. Simply click the button next to Google Maps to bypass Apple Maps altogether. It’s that easy.
