i believe the SD cards cannot be SDHC, for those of you who are having problems with yours.

 

You can use up to 4 gb SD cards but only have 512 files/folders on each card . With the cards full it does take a few minutes for the cards to load. I would only use good quality SD cards with any bit of equipment. Buy mine from Amazon, Trancend 4 gig are around £7. Do not use SDHC they will not work.

 

tried one of those as well, no luck. regular SD works like a charm. 2GB cheapo from local store
