This is what I remember also. In fact, I forgot and tried a 32GB card and it didn’t work. The folks at Labradar pointed my error out when I called them.Bought my SD card from LabRadar the same time I bought the the LR unit. It is a 16GB card and I believe that at that time LR stated that was the maximum size the unit supported. I have never tried a larger capacity SD card in mine so I really don't know for sure if it would work or not. The 16gb capacity is supposed to support 9999 series of 9999 shots each, so I've never bothered about getting anything bigger.
