Are your units compatible with the newer SDHC cards?
The answer to this question does depend on the model number of your product and also the software version you have loaded on your unit. SDHC is compatable with all 700, 800, 900 and 1100 series products with color displays with software version 3.7x0 or higher, On monochrome 700 series you would need version 3.8x0 and higher. The highest capacity we support is 32G. Older versions of software or older products will not be compatable.
