I have a 2003 tahoe with bose sound system. My friend and i installed the N3 and when we power it up neither disc will load. It says "insert approaite disk" then "reading disc" but then the message goes away and no action. It will play DVD's like it's supposed to but won't load GPS cd's. The unit is brand new out of the box with factory seal. I have also done the mod i found here and it also works great.
Second I have no sound, with my xm,radio,or ipod. Everything is registering on the screen and I can naviagte through. The only wire not hooked up right now is the vss wire. Does this matt
