What cards? My 8200 MK3 B works fine out of the box.

Mainly the CTCSS/DCS card, which feature the Icom has built in.
I don't know what, if any, benefit this would be in normal listening.

There are five cards in total available, but only on can be used at a
time in the 8200. I believe the base station version of the radio lets
you use more.
