Similar to how your contacts’ phone numbers are imported from your phone for easy access in the car, it would be useful to have your contacts’ addresses imported into the navigation system. They could then be selected as a destination (as a tab under “places”), or better yet via voice command, for example “navigate to John Smith’s home address” or “directions to dentist”.
Implemented around 6.0 or older by using the phone/contacts list. A navigate to button appears for the contact.
No, it doesn't, at least not for my car over multiple software updates and numerous trials. If you say "Call X" it searches your phone's contacts for a match to call first before searching the web. If you say "Navigate to Y" it only searches google maps, it does not search your address book. If the contact you are navigating to is also in google maps, like a business, it will work but not because of your contacts, because of Google maps.
Having to initiate navigation through the phone app rather than the navigation app, and not being able to use voice recognition for directions to a contact in the expected manner are more than small issues when it comes to usability while driving. The current setup is not intuitive, and therefore should be fixed.
