I have an lg motion with Google maps installed. For a good while now been using maps to get around town (I live in NYC). Maps had both the bus routes and schedule. About 3 months ago I heard there was Google maps version 7 was out but the play store won't update it. It showed open or uninstall. Maps 6 is great but about a month ago I found a maps 7 apk and downloaded it.
So with the update to google maps I think the people app integration is broken.
When I open a contact and click on their address I get only telenav, not google maps. I don't get the prompt for which app to use. And I checked app associations and mine is set to Maps for Maps and Physical Address. I tried to change it to Chrome for Map address but that didn't make a difference.
