Tuto for beginer

[Makina]

Hello,

I just bought a G01 X3, and my map is out of date. I allready donwlaod the map on a fat32 64Go usb key but I don't know how instal it ...
Before I had a F11 and it was easy on CIC...
I have a laptop with enet cable, and ISTA (reinghold) installed.
Do someone have a tutorial to show how to do ? 
I don't have carplay & screen mirroring, but my car is pre-equiped ! If you have also a tutorial for that ...

Thank you !
