I'm having a hard time understanding this. Why would Honda fit a PC Card slot in there? That's not exactly a mainstream memory card form factor. CF or SD, yes, but PC Card (which I assume you mean ~PCMCIA).

Or do they offer a PC Card memory card reader as a "dealer accessory"?

I'll take Ford's Sync with its USB port, even though I think the USB drive has to stick out of the dash, easily knocked and snapped in half.
