Navigation systems are updated on a yearly basis, the CF slot was only available for the 2007 year model and is now discontinued.cde2k7 wrote:It's a hard drive-based navigation system, and it's updated using the CompactFlash card slot.

I have no idea how accurate that information is though. Maybe someone else knows?
