Thanks
Called them, they said they would push the updates to the device but it said device up to date, then said downloading content but stuck on getting ready.
Let it do its thing, uninstalled cameras and then installed them.
Asked why the device had missed the updates and " it happens. "
Recently it has decided not to show cameras when driving at least twice, bit disconcerting as it could happen when using an unfamiliar route where cameras are but not shown.
