TBH there's no real advantage to inventing Bluetooth or optical processes when you've already got GPS available on many/most airframes and often that can be selected by a couple of key presses as the datum position for inertial align without needing to go down the road of entering figures long hand.
It just seems from what others have said that due to it's modification state this particular airframe lacked even the ability to align off a GPS Lat/long.

You are welcome. Pardon the thread drift but I recall the days of our navs babysitting/ nursing an early generation inertial and being quite chuffed if the terminal error was less than 10 miles after an 1 or 2 hour " trip"........how times have changed....
