 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!
