Excellent! That makes a lot of sense. Thank you for the post. My related question is, if you purchase two map cards, say a topo and a street, can you copy the contents of both cards onto one larger card and load both maps at the same time? Or are you stuck with one map at a time?
The street maps are locked to the sd card, they can not be copied. Not sure about the topo cards, you might be able to copy them.

To the best of my knowledge, I don't beleive that you can copy the topo cards either.
