Navigation on OS computers is only available as a route planner, but not navigation software. However, there are plenty of apps for iOS / Android.
However, if you want to see the navigation on the Mac monitor, you have to use a workaround.
The solution is called Reflector, currently in version 4.0 Download available. It runs on Intel and M1 processors under OS
Pure screen mirroring has the disadvantage that the entire screen is taken up by mirroring. Reflector displays a movable window of the mirrored device that can be freely positioned.
Since I have three monitors in the cockpit here to display the images from the three cameras (view left, rear and right) while driving, I want the navigation (here Magic Earth) to the right of the image from the reverse camera so that you can always keep it in view.
Reflector realizes this perfectly. The app's voice playback runs via the MacMini's integrated speaker or via Bluetooth, or the audio jack output to any output device.

How To
Screen mirroring is activated on the device whose screen is to be displayed on the respective monitor, the associated computer on which Reflector was installed and started is selected and the connection is waited for.
The cell phone or tablet window is now displayed on the monitor and can be positioned and scaled as desired.
