Mine is MY2009. The user manual says the card reader supports only SD cards up to 4Gb, and so it was before I got the radio software upgraded from 0210 to 0310. After the SW upgrade the radio supports also SDHC cards. I have tried 32Gb and 16Gb cards and they work fine now.
But, the manual says also that there are limitations such as: Max. 512 files in a folder / Max. 255 folders / Max. 2048 files and folders in total in the media. These limitations are features of FAT/FAT32 file system. Or, is there an update available on this with the newer cars (with SDHC support from the factory) or is the file system different with SDHC cards? I mean, when I have now upgraded the radio to support SDHC cards, are the limitations mentioned above different now?
When I downloaded music into the SDHC card, I realized that the 2048 limit (files and folders) was reached when about 16Gb out of 32Gb card had been used, so half of the card could not be utilized. Of course this depends on the file sizes etc. So I put the 32Gb card in my videocamera and used 16Gb card in the car in order not to "waste" space in the card.
