The .DAT file (that Greg speaks of) is necessary for the unit to display the snapshot...

Just as a test... I created a SNAPSHOT folder (on a SD card) and put 2 snapshots in it (1 snapshot with its associated .DAT file and 1 snapshot without the associated .DAT file)..

Then I put the SD card in my unit and the only snapshot that the unit would display is the snapshot that also had its associated .DAT file...

Open your SNAPSHOT folder on your PC and make sure there is a .DAT file associated with each .PNG snapshot...

What I find curious is kyrich says the snapshot thumbnail shows for a second on the snapshot view ...and then changes to a circle with a red line thru it....

My test above showed that my .PNG snapshot without a .DAT file does not display a thumbnail at all on the unit snapshot view...

The thumbnail/circle with a red line thru it seems to me that the .DAT file somehow became corrupted...
