Update, this morning my satnav database was on 21.9 so it's been updated online in the background as my memory stick hasn't been plugged in since my car was serviced.CJJE wrote: ↑Tue Dec 07, 2021 6:04 pmI have downloaded the updated maps to a USB-C memory stick, but so far the database id is still stuck on 21.2. I suspect that the system will only actually update the maps when it finds a difference between the local map stored and that on the memory stick. (I use a right-angle adaptor to store the memory stick under the sliding cover.)
So you can certainly see when the maps have been updated by comparing the database id on the Menu/Settings/System Settings/System Information screen. But in practice there is only new road near me that the maps don't show, and that was only opened a fortnight ago.
