Hi Everyone,

I have managed to get into the diagnostic menu of my Edge 800 using the following method:

Wrench -> System -> GPS -> View Satellites

Touching and holding the upper left corner of the screen brings up the diagnostic-screen.

However I don't see any option to run checksum. I assume the ESN number is the ID of the EDge, not the SD card?

Seems like the CID for Sandisk & KIngston MicroSd cards are printed on the front, although you will need a bright light & some sort of magnifying glass to read them.

The Sandisk CID is a straightforward 10 digit number, however the Kingston appears in the following format (letters & numbers changed):

1036sg293f

Any idea how that would translate to the 10 digit CID?

Can confirm the Sandisk works perfectly, but am still stumped with the Kingston, if anyone can shed any light on how to decipher the above number it would be much appreciated
