My trails and other added maps

[Scorpio49]

A few questions about adding maps to my new Dakota 20(first time user). If I install several state maps say Georgia and S.C. as well as My Trails, will My Trails  layer on top of both state maps? I had planned on putting the maps on the internal memory.

Also, if I install the state maps on an SD card and the My Trails map on the internal memory, will it be seen by the maps on the SD card?

Thanks

Yes, it will be on top.  And yes to the memory question
