Great thread, thanks everyone for the input. I work at Google (Cloud division, not Geo team), and I’m still perplexed. We just received delivery last weekend on a LC with the HUD (which is amazing). My wife and I both run iOS, and we both use Google Maps for directions. Strangely, I see the directions in the HUD, my wife does not, PLUS she is seeing a microphone icon where the center maps was previously. When she drives, the Maps feature is in the center of the dash but as soon as voice navigation speaks, it’s replaced with a Mic icon. Super annoying, and then the Maps disappears from the center.
I can definitely say that you do not need Full in the HUD settings to see the directions, mine is on Standard and I see them fine. You can have Maps in the center of the dash. When I drive I see a Map, but when I put in directions the map is replaced with directions, and HUD has a direction arrow (when you get a certain distance away).
I just checked and she is running an older version of iOS and Maps, which I am updating now and will test. The other possibility is I have two Google Maps apps on my iPhone, one that is Generally Available, and one that is Dogfood (pre-released). It’s possible that my Dogfood app has the setting.
If I can’t figure this out, I’m motivated to find someone in my company who can.
