I've been reading posts on several forums about installing an Aux input on my 2004 Z71, it is equipped with onstar but no XM radio.all i have is a HU with a 6 disc changer built in, no external tape or CD changer!
The Back of thre HU has the Black harness but only two orange wires.
some posted that the 4$ mod can not be done to a tahoe without XM however i still dropped the glove box and found the similar wires in a harness in the onstar unit, which are Black/white, Dk green/white, & brown/White has anyone tapped into these wires to get this mod done on a tahoe with no XM??
