"Chicklet"?
Saying microSD card is less confusing.
The old units (like the 800/810) needed the card for maps. They did not need them for routes (the internal memory was large enough for that).
The 1030 has a card slot but the internal memory is large enough for maps (generally).
The newer units (830, 1030+) don't have card slots (they have even more internal memory).
