It shoudl just be there so we must now ask what you're actually doing. You may not be properly finishing the operation.

 

I enter the destination and, after choosing the route and pressing the "Start" button, Google Maps starts to display the directions and indicates the kilometers to the destination, but it does not show the battery percentage upon arrival.

 

Try to reboot the infotainment system and also check if you granted all permissions to Google when asked to.

 

Thanks... i've done the reboot, but it remains the same!!! I will verify the permissions.

 

@eduspina, as you suggested, it was a problem with Google Maps not having permissions to access the vehicle data. Solved... thank you very much!!

 

Nice, glad it worked!!
Enjoy!!
