...essentially, if it's the same system as the '08 QX56 (I'm sure it is), then the CompactFlash limit is 2GB. Good thing I only paid $70. for the 16GB. Weird, 2GB is the limit for MS-DOS. That seems unusual if the system came with a 9GB hard-drive for the same thing.
There is a reference in the UG, not to disk size, but to Max files, which is 512. A quick check of math (avg 4MB per .mp3) = 2048MB. Makes no sense for such a sophisticated system to limit to such a small size.
