David,

I received the following tip on how the access the maintenance page from Jon
Hadlich:

 After the screen won't accept the card and it goes through the boot cycle,
- cycle power
-as the start up procedure starts you'll notice lines of text. As soon as
you see the bottom line of text ( it will say something like "blah , blah,
fixed disk" ) comes up push both encoders ( knobs on the front of the unit)
at the same time.
- this should cause the screens to go white and reboot.
-hopefully at that will bring up the ground maint menu
-if not try the hard boot procedure again

Subject: [LML] Chelton NavData updates

In the past I have had some issues updating my Chelton NavData.  If it
wouldn't update I would buy a new smart media card off of eBay and
everything would seem to work.

The last time I updated using the same card that I have been using for quite
some time without any glitches, it took 3 tries/reboots on each screen to
take(in the past I would given up and buy a new card but this time I kept
trying). The first 2 times the Cheltons just booted up as though there was
no smart media card in place though I'm sure it was put in properly.

Any ideas/suggestions.  Just a bit concerned that someday in the not so
distant future our wonderful Cheltons may be truly obsolete due to inability
to update the data.
