Mio168, can I put maps in main memory?

I bought a used Mitac Mio 168.
Came with a SD card with maps on it.
Mapping program is called Navman SmartST.
version 2.00.0029 sp1 us english.
Maps are (V2)

I need the sd slot for the wifi.
Can I move maps to main memory?
I have plenty of memory for what I need to do,
but can't figure out where to put the maps.
Tried the usual places: my documents, windows,
navman directory, root,...doesn't find them.
There's a dropdown listbox for "Active Map Selection"
but it's empty until you insert the SD card.

I can copy the maps to another SD card and it works...
so doesn't look like anti-piracy roadblocks.

I downloaded the manual for the 168. It only mentions
the GPS with zero info on how to use it.

Ideas?
Thanks, mike
