For some reason, even on the official Garmin CIQ site, there is no listing of which devices are CIQ 3 compatible.
I did find this list...

It says the Oregon 700 series and Rino 7 are both CIQ 3. Both do have large screens and the memory footprint for a DF is 124.7kb.
But when I select minimum SDK ver of 3 in the manifest editor, then those devices are not selectable as build targets.
Bug in the Eclipse editor, or is the list of CIQ3 devices wrong? Thanks!
