I suspect (and its just a guess) that the loading mech just transports the raw data to the mother board via the ribbon and the MB does all the processing, its just a case of sorting the correct protocol to and from the laser.loading mech.

The hardware is standard hardware, it is likely the interface and controller is standard as well.
So get hold of the specs of the DVD drive... who has access to the drive manufacturers specs?
And the drive simply delivers the DVD data over a parrallel interface to the main board.
So emulate the interface and you emulate the drive.
Ao you need to know the interface specs, and interface data protocol.
This is low-level hardware coding and physical design, not Visual Basic :-)
I think the interface is NOT IDE, PATA,SATA or SCSI because those are made for PCs with powerful, multipurpose PC processors, not dedicated controllers like in an automotive system.
And remember: the nav was designed in the early 90s and the DVD drive added in the late 90s. So think back 10 years as to what technology was available then...
