thanx garret... it seems that it cant be done... here i saw a pioneer working with another gps unit, connect to the pioneer with the rgb connection... they do this in imported cars here, but the z3 has not the rgb connection... if somebody thinks that can put brazil maps in a avic z3... i can pay some dollars $$$...
so thats it man, if you kown who wanna buy two z3 contact me... the hdd of the bouth units are unlocked, i can send it to US... in fact, i would like to change the z3 by two f9 series, becouse i can install brazilliam maps (igo) on it by the sdcard...
thanx man
