(Fig. 1) . The owner will have the option to update the radio or schedule the update for later. There
is not an option to decline the update indefinitely, the update must be performed.
NOTE: If the update is not performed the following will occur.
On November 3rd, 2019, all vehicles GPS functionalities (i.e. location, turn-by-turn, date, time) will

How can this apply only for the US when there is Canadian sales with the exact specs? Does that mean our GPS will remain inaccurate?

I guess that explains why I did not receive any message to update my 2018 GC.
You could always just go here and put in your VIN -- they will let you know if there is an update available for your vehicle.
