You have to install a program onto a computer and download the update there, transfer that to a memory stick and put that into the car. I had to sit in the car and have it running whilst it installed.Ok thanks _Emma.
Just one thing how do you do the update? Is it downloaded to your mobile then up loaded to the infotainment unit. I know you don't recommend doing yourself but if it's something you can do yourself I'm interested.
Download was 57GB to the computer. 27GB to the memory stick and about an hour sat in the car. It’s not difficult but definitely carve out a decent amount of time if you want to do it yourself.
