Good question. I have not determied what type card it is yet.
However, it does appear on the outside to be the same as those in the
Garmin 250 XL(?). Aircraft Spruce sells a reader for whatever type
card that is for about $40 USD. It is not a Compact Flash, SD or xD
card.

Not sure about the 430 but the G1000 appears to be SD cards. However,
I've not tried to pull one out.
