I checked my version and the SID/STARs work fine and I have updated recently up to AIRAC cycle 2008... the SSG B748i does have an odd navdata arrangement, it overall uses the X-Plane navdata, but there is an on board the aircraft version as well version noted as cycle 1707, there is an installer in the NavData installers folder.... I think you can update this by downloading it from Navigraph
