Hello...

If you have a 530 or 430, does it accept the same updates? Or are the
updates specific to each machine. Also, if you have both in your
plane (one of each), do you have to purchase 2 updates?

Jepp sells a discounted "two unit in same aircraft" package for the
GNS400 and 500 series. I'd expect that package ($480/yr instead of
$365 each US for the americas coverage) would cover both units in the
same aircraft regardless of what combination of 400 and 500 series
units are installed.

You need to purchase the special Jepp programmer - unlike the G1000 it
won't work in a normal card reader.
