The 6 digit number you want is the master key and will factory reset the radio, this is what toyota use.

Essentially Resetting the stereo will cost $66, as they have to plug it into a machine that has a limited number of resets available (after which they have to send it off to have more resets programmed in or something – almost like a prepay phone lol).

I know that no machine is required to input the master key, just follow " Kiloxray" information but the master key is model dependant

You could try contacting fujitsu ten and see if they will give you the code... unlikely but worth a try....

Just about all the fujitsu radio's that i have worked on do not have a code supplied or turned on from the factory, it is a user option to activate the security code and  the 3 digit number is chosen when activating this option so i doubt the dealer would have it.

Having the the dealer or fujistsu ten resetting the radio is normally the only option if you want to keep this stereo.
