It’s been a while since I’ve updated maps/software, but I’m fairly sure it’s all contained in the same file- so if your car is already up to date, nothing changes. If not, the X GB file will do it for you.
You can check your units current software version on an info screen in settings (somewhere) and then google it, to see if it’s current.
