The manual states that a long press of the voice button on the steering wheel should trigger the phone's voice command system. This seems to work fine with my wife's iPhone, but not with my Samsung.
When I connect her iPhone via BT, an extra box called Siri appears on the Phone page of the Sync display. Also, holding the voice button on the steering wheel pressed for more than a second triggers Siri.
When I connect my Galaxy S5 with Android 5.0 via BT, nothing special appears on the Sync display, and holding the button pressed longer does absolutely nothing.
What's the catch? Is there anything special I should configure on the phone?
