Map Update authentication Algorithm

[arkalos]

Hello!

 

I was wondering if any1 ever bothered on finding the algorithm that gives the

unlocking code for the dvd map upgrades for the Z*/HD* avics....? That would

make the map upgrades installable to more than one unit since you wont have

to fetch the unlock code via pioneer's website which marries the media's serial

along with the hardware serial thus forbidding further use of the same media :/
