On the basis of the above, I had assumed that I would simply be able to transfer my SD card over. However, on checking the Owners Manual, the only hardware mentioned is the two USB ports. So, the only way to hardwire anything would be via them, with the simplest (non-device) options being either an SD card adaptor or a USB drive. Unfortunately, the manual also recommends using an extension cable for such connections, in order to protect the ports from damage, which will be a much less satisfactory solution, compared to simply placing an SD card in a slot in the glove box, which is rather disappointing.
