map update

[ZKAR]

want to update the map for in-car nav system of 2018 Jaguar Portfolio.

Apparently, that means having a sim card in the centre console slot & cant be updated through the USB socket. Why is it made so complicated?

can anyone advise what sort of sim is compatible. Shops just look blank when I say I want it for a Jaguar!

Thanks. Barry.

I have a 2017 XF and I too cannot find a new or used map card. unless you pay Jag almost £200. Total rip of price. Have you had any luck?
