IIRC, from the beginning, Android Auto headunits have been able to use an onboard GPS antenna to supplement the phone's built-in receiver. I guess the theory being the vehicle mounted antenna can be both more sensitive and also better positioned to see the sky than wherever your phone might end up sitting in the vehicle.
Another possible explanation is from their AA introduction, Pioneer included a navigation option in the description of their low/mid range AA units. At least once upon a time, the higher end AA units also had built-in navigation for use instead of AA maps, if you preferred. I've never actually seen the navigation add-on item(s) for sell anywhere, though.
One has to remember that when AA was originally introduced, Google Maps and Waze didn't have offline modes. No network, no navigation. I think earlier phone hardware also had less robust GPS reception making it more dependent on network location services and/or benefiting more from an external antenna than current phones do. As people became more dependent on phones for navigation, the hardware got better, just like the cameras.
Or I could have dreamed all of this...
