When I turned on the ignition, the Nav was already in the process of upgrading.
May be try that sequence. Let it sit for a while, then pop in the CD before you turn on the car. May be worth a shot.
I have an MK4 though and according to UCrewX5, MK4's recover from a bad OS upgrade much better than the MK3's. Hope you can get yours working.

If it is MK IV just do it the ordinary way,
Open drivers dor turn ignition to 1 (acc)
Open trunk insert cd
Do not turn off ignition, close drivers dor or trunk untill you are asked by nav to eject cd
Be patient, it might take MK IV few minutes before you se update beeng loaded on the screen
If the power light is off and only turns on as you press or hold ejrct button, check ther fuses too
