How do I enable the GPS system of Mercury Mountaineer in Saudi Arabia?

I have Mercury Mountaineer from USA and I need to reactivate the GPS the navigation system in my country (Saudi Arabia) or in the Middle East region.

reactivate is not the right word/term.
sattellite put it immediately in activation, whithout your help, anywhere, like your cellphone. obtain an autorisation is a question of goverment, and not of gps.
is someone told you that you need a code or to pay a reactivation ?
mercury is it allowed in saudi arabia ?
the best way to be in a legal way whith gps is : to let professionnal service of mercury do it for you.(frontier and border are still dangerous...)
