Hi Omar; I'm facing the same problem ....I think we must update the ROM version of the Navigation system....done by removing the whole unite and flash the ROM which is attached to the back of the screen ....actully they did the same thing for my car and Its in Km not Miles and tept.in C not F by flahing the odometer ROM from behind in a private carage in Sharjah/UAE.... They couldent do the same for Navigation Syst coz its need special conectors!!!! and the Gulf ROM software.
Pllz keep in touch if you find a solution.
