Read this on another forum, don't know if this will work
To update the firmware without applying a welcome screen or other hack, here are the steps.
1)Copy the following files from the navigation DVD that contains firmware you would like to use to a CD-R (every navigation DVD contains copies of system firmware, the newer navigation disc have newer firmware images):
BN2HH12C.BIN
BN2HH110.BIN
BN2HH120.BIN
BN2HHMLD.BIN
BN2HN12B.BIN
BN2HN18B.BIN
BN2HN380.BIN
BNHH401A.BIN
BNHN404A.BIN
2) Insert the original navigation DVD back into the DVD-ROM in your car.
3) Start the car normally, and at the main navigation screen hold Map/Guide, Menu, and Cancel for 5 seconds, this loads a debug screen \ menu.
4) Hit the "Version" button on the touch screen in the debug menu.
5) Take the original navigation DVD out of the car and replace it with the CD/DVD you just created (burned).
6) Hit the "Load Disc" button on the Version screen.
7) It should take about 20 seconds for your car to load the new BIN (firmware) and reboot. Once that happens, take out your burned CD/DVD and put back the original navigation DVD (the DVD you copied the firmware image filles off of).
8) If anything goes wrong, remove the ground to the battery for 30 seconds with the original DVD in the car. The old OS will load back on the system.
So say you have a new navigation DVD, ver 3.8 for example, you could copy the above firmware files to a CD-R and preform the method above to update just the system firmware from a CD-R instead of the new DVD navigation disc. This will not really get you anything though because once you insert the old navigation DVD in the drive it will recopy the firmware off the disc if different. This is only helpful if the system checks the navigation disc for PTP validity during a firmware update only and not on ever access, then you would have a way of getting around the PTP check and use a backed up DVD.
It would be interesting to try updating the firmware separately with a CD-R to the new navi DVD firmware just to see if it will then take the new navi DVD after a firmware update to the latest firmware, I doubt it though
