AFAIK, every single one of those "built-in navigation/maps" either require the car itself is internet connected (with its own modem), or that you every year get a SD card with map updates to stick into the car.

I guess it's fine in an emergency, but I wouldn't want to use it day-by-day, the live traffic/road closure information in my case ends up saving us tons of time over the year.

Mine is from 2013. There is no longer map updates for the built in nav system.

So I bought an Android auto / Car play module that integrates with the car touch screen. Now I have up to date maps and navigation for ever. :)

My 2019 Subaru legacy supports auto and does not have built in navigation. The aftermarket dashboard display in my 2011 Ford ranger also supports android auto but has no built in GPS.

Mine (a US 2017 subaru impreza) supports both and doesn't have built-in navigation/maps.

Yes. I can't remember which cars (some base-model Hyundais I think) but I know I've rented a few that did have Android Auto but did not have any navigation included.
