Hi Michael.
I too have just had a similar issue after buying my first Jaguar (Blue XE).
I bought a 32gb stick only to get the the message telling me there was insufficient space!
Make sure you buy a 64gb USB 3 memory stick. I tried to install the maps off a USB 2 memory stick I already had but it failed twice at 3%. The USB 3 stick worked first time.
I think it's a mad that you have to download the map direct to the memory stick. My PC does not have USB3 ports and it took about 4 hours!
Best of luck. 👍
