Jeppesen's site requires the "System ID" for their database updates and I cannot find the System ID for the GNC-250XL. Did such a thing even exist when the 250XL was manufactured? If their is such a thing, does anyone know how to find out what it is? Jeppeson's info does not list the 250XL in the "how to find system ID" info.
