I would like to have an idea of the size of the downloads when the car updates. I realise that there will be some variability but a general idea would be useful. Does anyone know? Our Wifi runs from a 4G router and we have a capped data limit. I usually monitor this but had not done so recently. I looked yesterday to see how we are doing this month and our usage has been massively higher than usual. It could be other factors but I would like to rule out what the car is likely to be using. I am trying to account for about 30GB and I was reckoning a download for the car is unlikely to be anything like that (though I note there are maps updates too).
