I'm sure everyone knows that the voice of the stock navigator can be played through the speakers without the stereo being turned on.
Does anyone know what is the wiring diagram?
Is the stock nav voice wired directly to the speakers or is there a separate input jack through the stock stereo?
This is just for my understanding for future reference if I want to upgrade the stereo, speakers and cables.
Also, does our stock speakers (Premium Package) have built-in amp?
Thanks much in advance.
