Upgrading SatNav on T6.1 with SD card?

[This is the life]

Does the T6.1 California have an SD card and if so where is it? I'm wanting to upgrade the SatNav so that the new 20 MPH speed limits in Wales show up as they do on my Citroen.

I think you have to use the usb - c.

not sure if that is 100% correct.

Brilliant, thank you.
