That's strange. I can't seem to reproduce that behavior. My desktop PNDs show up fine. Installed PNDs (on the active device) won't show up in the install tab by design (which is not hammered down though), but they should show up in the launcher. Could you PM/post me your pnd_run log file (in /tmp after running) and give an example of a PND that you have in your pandora/desktop directory?
