If its setup correctly with your phone plugged into the car USB port or if wireless(is the car compatible with wireless android auto as mine isn't?) is possible it should work instantly assuming you have
DATA on your mobile and followed all instructions correctly as its pretty easy.
You install the APPS you wish to USE ON your phone.
I recommend WAZE for Satnav, it's owned by Google and also free but it'll give you live traffic reports and speed cameras.
