Porsche Cayenne 2008 Turbo GPS Issue

Hi all,

A friend of me has bought a Cayenne Turbo, the car came with a old GPS release like same year of the car, means 2008.
I updated GPS with 911 Turbo DVD provided in forum, thank to him but GPS still didn't work at all means GPS is not able to recognize current localization. It seems there is chip into spoiler, but from my information there is one chip for US and one for Europe.
Someone has already meet this issue? Or know the way to reset GPS to have the correct location?

Thanks in advance.
Cheers!
