Maps+, Android Auto, etc not integrated with HUD

New Contributor


I just saw Maps+ is included in my active plan on my 2020 Sierra. Overall, it seems solid, but we'll see as I get more time with it. I noticed that there are a few issues. A good first version, but there are some updates/improvements needed to really make it a go-to over plugging in my phone for google maps on android auto

1) It does not replace the built-in nav, which is fine, but it does not even get priority over the built in navigation. So when I use voice commands, it does not go to Maps+. I cannot make the navigation button at the bottom of the screen go to Maps+.

2) It does not work with the HUD. This has been a huge complaint for me with this vehicle. I've been in several other vehicles that will relay the turn by turn directions onto the HUD (like the built-in nav does) from android auto or carplay, but my sierra does not. I know the phone can relay this information to the vehicle because several other vehicles do this. I was hoping that by having Maps+ be a built-in navigation app that it would gain this feature, but to my disappointment, the HUD still will only show the built-in nav directions. Why does this matter? Well, I tow a lot and utilize the camera feature, which you cannot use if you need to see directions. Or as you switch lanes, the side cameras come up, taking away navigation, so when you're switching lanes for interchanges, you have to manually close the camera view to see which exit you're having to take. If the HUD or the cluster would simply show the next instruction from the 3rd party navigation app like so many other vehicles do (my 2016 accord does this), it would be a huge improvement to quality of life while towing.

3) Maps+ does not appear to have access to contacts, or the remote app. Sending an address to the truck results in the built-in nav being used, not maps+. I cannot search for home addresses for contacts that are stored in the head unit, or on my phone. This means I must manually type in the address or speak it with the voice assistant every time. Kind of annoying. 

4) I haven't found it yet, but I'm assuming there's a way to save home/work addresses like the built-in nav or google maps.

From here, you'll select the ‘Favorites’ button, where you're taken to the Favorites screen. You will be prompted to ‘Set Home’, ‘Set Work’ or "Add Favorite". Tapping on any of these buttons takes you to the search bar, where you'll search for and confirm the respective location.


You can also set home, work or favorites from the POI cards. If a destination is not yet selected as home, work or favorite, the heart icon appears on the POI card. Tapping on this icon brings up a full-screen modal that enables the user to set this location as either Home, Work or a Favorite.
