Yeah, the pdf. alluded to in the iRV2.com thread I referenced above talks about there being a technician-only code as of 2004, so perhaps someone at Monaco or BCS would whisper it into your ear, seeing as how Alladin isn't made anymore. Threads indicate there is also an adapter that can send your new sensors' data into the Alladin, but if you want it for a backup, you just need to calibrate it and forget the adapter route.
