John,

It's very easy to "fry" these cards. inserting or removing them with power
applied to the system is a common/popular way! L It appears they can be
damaged by other means as well, as I've lost two over the past year, and
have been very careful! I expect that's one reason they never became a
popular standard? Ref Chelton Installation Manual 64-000038, Page 71 of 172.

I've been able to find these on ebay from time to time; that's the best
source I have. I am down to two cards now, and am considering a conversion
to the mini-xD card. Some folks have modified a "tray" that duplicates the
SmartMedia card interface and holds the mini-xD card. Seems you need to
modify the "tray" a bit by grinding on it so it will fit into the slot in
the Chelton screen, but you might check the older LML posts re this?

If you buy SmartMedia cards via ebay or other, consider going for the 32 or
64 MB chips. 16 MB is marginal for the newest Chelton data loads, and I had
some trouble.so no longer use them. The Chelton will take 64 MB cards; I
have not tested larger capacity cards.

One other note. You need to load updated nav data into all Chelton screens;
it does not automatically exchange this with multi-screen systems. My CPU #1
(PFD) will normally go into the data/menu functions just by inserting a
"readable" card and then turning on the power, but I must also hold down the
"fast erect" button during power up to cause CPU #2 (MFD) to go into this
mode. This was passed to me by another Chelton owner; the above installation
manual does not mention this requirement in the set up/configuration
instructions starting on page 71, but does note this requirement as step
4.1.2/4.1.3 on page 140. Give this a try; it works for me.

Hope this helps!
